Understanding Habitats and Food Webs

The video explores the concept of habitats, using a polar bear in the desert as an example of a mismatch between an animal and its environment. It explains how habitats provide food, water, shelter, and space, and introduces the idea of food chains and food webs. The video compares food webs in different habitats, such as forests and the Arctic, highlighting the unique adaptations of animals like polar bears to their environments.

Why is the polar bear unhappy in the desert?

• Because it loves the forest

• Because it is too cold

• Because it lacks its natural food sources

• Because it prefers the ocean

What are the basic needs of animals in their habitat?

• Shelter, toys, and food

• Water, sunlight, and warmth

• Food, friends, and fun

• Food, water, shelter, and space

What is a food chain?

• A group of animals that live together

• A type of plant found in the desert

• A list of animals in a habitat

• A model describing the flow of energy between living things

How are food webs different from food chains?

• Food webs only exist in the ocean

• Food webs are only about plants

• Food webs are a collection of interconnected food chains

• Food webs are simpler than food chains

In a forest habitat, what role do decomposers play?

• They create energy from the sun

• They are at the top of the food chain

• They break down matter and provide nutrients for plants

• They eat only plants

What is the primary producer in the Arctic food web?

• Polar bears

• Seals

• Zooplankton

• Phytoplankton

Which animal is at the top of the Arctic food web?

• Beluga whales

• Polar bears

• Zooplankton

• Humpback whales

Why do decomposers in the Arctic break down matter more slowly?

• Because of the lack of sunlight

• Because there are more plants

• Because of the cold climate

• Because there are more animals

What affects the types of plants and animals in a habitat?

• The amount of sunlight

• The number of animals

• The presence of humans

• The habitat conditions like land and water availability

Why is the polar bear well-suited to the Arctic habitat?

• It can live anywhere

• It eats only plants

• It has adaptations for the cold and fits into the food web

• It prefers warm climates
