Regions Overview

Animals are not found evenly across the world. Different regions support different kinds of wildlife because of variations in climate, geography, and ecosystems. These conditions shape where animals can live and how they survive.

Over time, natural features such as mountains, oceans, and deserts have separated animal populations. This separation has allowed species to adapt to different environments, leading to the wide variety of wildlife found around the world today.

Each region includes a mix of habitats—such as forests, grasslands, deserts, mountains, and oceans—that provide food, shelter, and space for animals. Some species live across large areas, while others are limited to very specific regions.

For example, kangaroos are found only in Australia, polar bears live in the Arctic, and many lemurs are found only on the island of Madagascar.

List of Regions

The regions listed below are based mainly on continents, along with a few unique areas such as the Arctic and Antarctic. This approach provides a simple way to organize the world and understand where animals are found. While there are many ways to divide the Earth into regions, this guide focuses on broad, familiar groupings that make wildlife easier to explore.

Africa

Regions, Ecosystems and Habitats

For most of human history, people depended directly on the ecosystems and habitats around them for food, water, and survival. If resources were limited, people had to adapt or move.

Today, farming, trade, and technology allow food and materials to come from many different regions, making that connection less visible. But it is still there. Humans still depend on healthy ecosystems and habitats for survival—either locally or from other parts of the world.

For example, avocados may be grown in Mexico and shipped to other countries. If drought, soil problems, or other environmental changes affect the ecosystems where they are grown, production can be reduced or disrupted. Similar patterns apply to crops, fisheries, and water supplies.

Regions and Animals

Animals play a role in maintaining the balance of the ecosystems where they live. Those ecosystems are connected to other ecosystems through water, climate, and the movement of species.

This means changes in one place can affect other places. Even if those connections are not always easy to see.

Here are some examples.

Whales

Whales may seem far away from human life, but they are part of ocean systems that support many other forms of life. Here is one example of how that works:

• Whales feed deep in the ocean.
  Many whales dive to eat krill, small fish, or squid that live far below the surface.
• They return to the surface to breathe.
  When whales come back up, they release waste near the surface of the water.
• Their waste contains nutrients.
  These nutrients, including iron and nitrogen, help support the growth of other living things.
• These nutrients help tiny ocean plants grow.
  Near the surface, sunlight allows microscopic plant-like organisms called phytoplankton to grow.
• Phytoplankton support the ocean food chain.
  Small animals eat phytoplankton, fish eat those animals, and larger animals eat the fish. This supports many forms of marine life.
• Phytoplankton also produce oxygen.
  Like plants on land, they release oxygen as part of making energy from sunlight.
• Oxygen is important because living things depend on it.
  Most animals, including humans, need oxygen to breathe and survive.
• This means whales help support larger ocean systems.
  By moving nutrients to the surface, whales help support phytoplankton, which supports marine life and contributes to oxygen production.

Polar Bears

Polar Bears may live in the Arctic, but because of their food source (seals) they are connected to life all over the world.

• Seals depend on fish and smaller marine life.
  These fish depend on even smaller organisms in the ocean.
• This creates what is called a food chain.
  Each level depends on the one below it for energy and survival.
• Polar bears are at the top of this chain.
  An animal at the top of a food chain is called an Apex Predator.
• Apex predators help control prey populations.
  By hunting seals, polar bears limit how many seals are in a given area.
• If seal populations grow too large, they can use more food than is available.
  For example, a large number of seals may eat more fish than the ecosystem can replace.
• This can reduce food for other species.
  If fish populations decline, it can affect other animals that also depend on those fish.
• A balanced system means populations stay within levels the environment can support.
  There is enough food, space, and resources for different species to survive without one group overwhelming the others.
• This leads to a more stable ecosystem over time.
  When populations are balanced, the system is less likely to experience sudden changes or shortages.
• These systems are connected to other ecosystems beyond the Arctic.
  The fish that seals eat are part of larger ocean systems. Many fish species move across wide areas or are part of ocean currents that connect different regions.
• Changes in one part of the system can affect other areas.
  If fish populations are reduced in one region, it can impact food availability in other parts of the ocean where those same species are found.
• Ocean systems are part of a global network.
  Water, nutrients, and marine life move through currents that connect the Arctic to other parts of the world’s oceans.
• This means balance in one region supports balance in others.
  When Arctic food systems remain stable, it helps maintain the flow of energy and life through these connected ocean systems.

Lions

Animals like lions help maintain the structure of ecosystems by influencing multiple levels of the food chain.

• Lions hunt large herbivores.
  In African savannas, lions hunt animals such as zebras and antelope.
• These animals eat plants.
  Herbivores depend on grasses and other vegetation for food.
• Lions help control herbivore populations.
  By hunting, lions help prevent herbivores from becoming too numerous. This creates a more balanced ecosystem. When plants, herbivores, and predators are in balance, the system is more stable.
• Healthy vegetation also supports the land itself.
  Plant roots help hold soil in place and reduce erosion, especially during heavy rains.
• Vegetation helps manage water in the environment.
  Plants absorb and slow down water, helping it soak into the ground instead of running off too quickly.
• If vegetation is lost, these systems can break down.
  Overgrazing can lead to soil erosion, poorer soil quality, and less ability to hold water.
• These changes can affect nearby areas.
  Soil and water do not stay in one place—erosion and water flow can impact rivers, wetlands, and neighboring ecosystems.
• Land ecosystems are connected across regions.
  Rivers, weather patterns, and animal movement link one area to another. Changes in one location can influence conditions in surrounding areas.
• This means balance in one area supports stability in others.
  When vegetation and animal populations are maintained in one region, it helps protect the health of connected land and water systems.This means apex predators play an important role.
• This helps protect plant life.
  If too many herbivores are present, they can overgraze and damage vegetation.
• Healthy plant life supports other species.
  Plants provide food and shelter for many animals and help maintain soil and water systems.
• This creates a more balanced ecosystem.
  When plants, herbivores, and predators are in balance, the system is more stable.
• This means apex predators play an important role.
  Animals like lions help maintain the structure of ecosystems by influencing multiple levels of the food chain.

Every region of the world supports its own web of life, shaped by climate, geography, and time. From forests and deserts to oceans and polar ice, these environments are connected in ways that are not always obvious—but those connections are real. Understanding where animals live and the role they play in these systems helps explain how these systems support food, water, and the conditions humans depend on to survive.
