Photosynthesis
What is the main consequence of removing a species from an ecosystem?
Decrease in the number of animals that would normally eat it
What is the primary reason why organisms only consume a small part of the energy stored in their food?
Energy is used for life processes such as movement and reproduction
Why does introducing a new species into an ecosystem lead to changes in feeding patterns?
New species often prey on existing species

What percentage of energy from the Sun is available to Quaternary Consumers in an energy pyramid?
1%
Why is the bulk of the energy received from the previous trophic level used by organisms?
For movement, growth, and reproduction
What type of ecological pyramid displays the amount of energy stored in different trophic levels?
Energy Pyramid

Decomposer
What is the primary characteristic of a herbivore?
Eats plants
In a food chain, what do the arrows typically represent?
Direction of energy flow
What happens when one link is broken in a food chain?
Impacts the entire food chain
What is the significance of trophic levels in a food chain?
Shows how energy is transferred between levels
Test your knowledge on different categories of consumers such as herbivores, carnivores, omnivores, detritivores, scavengers, and decomposers. Also explore the concept of food chains and how energy flows through ecosystems.
