What is the source of energy in photosynthesis?
Sunlight
The herbivore trophic level
Primary consumer
Allows different species to colonize different parts of the intertidal zones
Niche Partitioning
Honey provided by wild bees
Provisioning
Organisms that cannot produce the nutrition they need through photosynthesis.
Heterotroph or consumer
Where does most of the energy released in cellular respiration go?
Lost as heat
When drawing out the food web below, which way should the arrow point?
Eagle Snake Mouse Grain
To the left (towards the consumer)
A species that has an outsized role in its ecosystem
keystone species
Regulating
Consumers that release nutrients back to the ecosystem when they consume the wastes of or remains of dead organisms.
What are decomposers.
Energy stored by plants
Net primary productivity
What percentage of energy from a PRIMARY PRODUCER is available to a PRIMARY CONSUMER?
10%
Water in a desert or amount of sunlight on the floor of a rainforest
Limiting factors
Cycling of nutrients through multiple ecosystems
Supporting
Orchids grow on trees and do not take any resources from the tree
Commensalism
Which organisms perform cellular respiration?
All of them

What is biomass?
Example of a keystone modifier
beavers damming rivers; animals burrowing holes used by other animals;
Coral reefs are home to 25% of marine species
Supporting
An organism that makes its own food
Autotroph or producer
This process converts chemical energy into useable energy
Cellular respiration
