Study Notes
What a Habitat Is
- A habitat is the area where something lives.
- Animals rely on living and non-living things around them to survive.
- Animals require food, water, shelter, and space to live.
- Food for animals comes from other living things in their habitat.
Food Chains and Food Webs
- A food chain is a model that describes the flow of energy between living things.
- Most animals don't just eat one thing, so they are at the top of multiple food chains.
- Food chains overlap and are tangled around each other, forming a food web.
- Food webs are big, tangled systems that include every plant and animal in a habitat.
Food Webs in Different Habitats
- Food webs and the ecosystems that support them look different in different parts of the world.
- Changes in habitats affect what kind of plants and animals live there.
Forest Food Web
- Plants (trees, grass) change energy from the sun into sugar.
- Some animals eat other animals
- Owls eat mice or rabbits
- Snakes eat squirrels
- Owls eat meat eaters, like snakes.
- Decomposers (insects, fungi, and bacteria) break down whatever’s left over and provide nutrients for the plants.
Arctic Food Web
- Phytoplankton convert energy from the sun.
- Zooplankton eat the phytoplankton.
- Small fish eat the zooplankton.
- Larger fish eat the smaller fish.
- Beluga whales eat fish, while humpback whales eat plankton and krill.
- Seals eat Fish.
- Polar bears eat seals and whale carcasses.
- Decomposers: bacteria break down matter slowly due to the cold.
How Conditions Affect a Polar Bear
- Polar bears fit into the arctic food web perfectly
- The available food has enough fat and protein to keep its energy up.
- Polar bears have the body adaptations to survive and feel comfortable in the cold.
- Polar bears aren’t built to survive in the desert or the forest.
