Flow of Energy in an Ecosystem
An owl gets its energy from a field mouse it eats. From which food source did the mouse most likely get its energy?
Grass
A food chain in an ecosystem includes blackberry bushes, deer, and wolves. Deer eat blackberries. Wolves eat deer. If the population of wolves decreases, how will this affect the population of blackberry bushes?
It will decrease because there will be more deer.
How would the woodpecker population in a forest area most likely be affected if a housing development is built in that area?
They would experience a decrease in available food.
deciduous forest
A biome with four seasons, plants shed leaves in the fall and grow new ones in the spring.
What would most likely happen if there were no plants left in an ecosystem?

Decomposer

Producers
Organisms that make their own food
grasslands
a large open area of country covered with grass, especially one used for grazing.
Tundra
a vast treeless plain in the arctic regions between the ice cap and the tree line
Which would most likely cause a decrease in a population of herbivores?
an increase in the number of carnivores
tropical rainforest
biome near the equator with warm climate wet weather and lush plant growth
Which most influences a forest ecosystem's ability to support life?
the amount of sunlight and the type of soil
What will be most affected if the decomposers in an ecosystem are removed?
the quality of soil
