Producers
The main energy source for the biosphere
Sun
The process through which producers make their own food
Photosynthesis

A group of lions and hyenas living in an environment are competing for the same prey. What level of organization best describes this group of organisms?

An increase in rain in the desert will promote plant growth, which will feed the consumers, resulting in an overall increase in biodiversity.

I have cell walls, cannot move, and I gain energy by breaking down dead organisms. What am I?
Mushrooms/Fungi!
I have cold temperatures, long winters, and convered in evergreen trees. What biome am I?
Taiga
How might an abiotic factor such as rising temperatures the ocean affect biotic factors (in the ocean or on land)?
1. Biotic factors (aquatic plants and animals) will have to adapt to rising temperatures, or they will die.
2. Rising temperatures will cause the ice caps to melt, which will flood coastal cities. This will hurt humans (biotic).
As you move up the energy pyramid, _________% of energy is lost.
90%
What happens to energy when you reach the tertiary consumer in a food chain?
When the animal dies, decomposers break it down into soil. That matter and energy feed the plants and continue the cycle.
