What is the difference between a biotic and an abiotic factor in an ecosystem? Give an example of each from the video.

Biotic factors are living things, like ants or plants. Abiotic factors are non-living things, like humidity or sunlight.

The video described an energy flow in the ecosystem starting with the sun. List the four components of the energy flow described in the video.

The energy flow described in the video is: sun, sunflower, grasshopper, and toad.

All the different populations of organisms interacting with each other.

I can describe the different parts of an ecosystem.

1
Biotic factors are living things in an ecosystem, while abiotic factors are non-living things like humidity.
2
Producers, like trees and bushes, create their own food, while consumers, like spiders and snakes, eat other organisms.
3
Energy flows through an ecosystem, starting with the sun, then to producers, then to consumers like grasshoppers, toads, and snakes.
