Food Chain/Energy Pyramid
The first trophic level with the greatest amount energy.
Producers
The source of energy for this trophic level.
Another word for consumer in an ecosystem.
heterotroph
What are the main types of decomposer organisms?
bacteria, fungi(mushroom), earthworm (atleast 1 of these to be correct)
all living or once living parts of an ecosystem
biotic factors
The direction of energy transfer is represented by this.
Arrow
Which trophic level eats producers only?
primary consumer/second tropic level
What type of consumer only eats plants?
herbivore
How does the activity of decomposers impact the health of an ecosystem?
recycling nutrients back into the ecosystem
all non living factors in an ecosystem
abiotic factors
Trophic level
The process by which producers transform sunlight into chemical energy.
Photosynthesis
What type of consumer eats both plants and animals?
omnivore
How do decomposers contribute to the cycling of nutrients within an ecosystem?
by breaking down dead organic matter into simpler inorganic compounds that can be used by producers.
abiotic factors
The amount of energy that is transferred from one trophic level to the next?
10%
What do producers need to perform photosynthesis?
sunlight, water, carbon dioxide
Deer, rabbit, squirrel are all considered to be part of what trophic level?
primary consumer
Explain the difference between a decomposer and a scavenger.
Scavengers consume larger pieces of dead organisms, while decomposers break down the remaining organic matter
Trees, grass, deer, insects
A model of energy transfer that can show how the food chains in a community are interconnected
Food web
oxygen, glucose(sugar)
shark, killer whale, lion could be apart of what trophic level?
tertiary or apex
Why are decomposers not typically placed on a single trophic level in a food pyramid?
Because they feed on dead organisms from all trophic levels, meaning they can be considered to "cross" between different levels.
what happens to nutrients in an ecosystem?
they are recycled and used again
