Energy Acquisition in Living Things

The video explains how living things obtain energy, starting with the sun. Plants convert sunlight into chemical energy, which is then consumed by animals. Animals are classified based on their diet: herbivores eat plants, carnivores eat meat, and omnivores eat both. The video illustrates energy flow in an ecosystem using a simple model involving an apple tree, insects, a raccoon, and a hawk.

Why do living things need to eat?

• To grow in size

• To socialize with others

• To gain energy for survival

• To enjoy different flavors

What unique ability do plants have regarding energy?

What might happen to a raccoon if it leaves the safety of the tree?

• It might turn into a plant

• It might find more food

• It might get caught by a hawk
