10 Questions
What is an ecosystem?
A structural and functional unit of ecology where living organisms interact with each other and the environment
How do animals influence the movement of matter and energy in an ecosystem?
By feeding on plants and on one another
What do decomposers do in an ecosystem?
Break down dead organic matter and release carbon back to the atmosphere
What controls the overall structure of an ecosystem?
External factors such as climate, parent material, and topography
How are ecosystems linked together?
Through nutrient cycles and energy flows
What is the role of animals in the movement of matter and energy in an ecosystem?
Animals play an important role in the movement of matter and energy through the ecosystem by feeding on plants and on one another.
How do decomposers facilitate nutrient cycling in an ecosystem?
Decomposers facilitate nutrient cycling by breaking down dead organic matter and converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes.
What are the biotic and abiotic components of an ecosystem?
The biotic components of an ecosystem include all the living organisms, while the abiotic components include the physical environment with which they interact.
What are some examples of internal factors that control ecosystems?
Internal factors that control ecosystems include decomposition, root competition, shading, disturbance, succession, and the types of species present.
How does energy enter the ecosystem?
Energy enters the ecosystem through photosynthesis and is incorporated into plant tissue.
