Carbon Cycle
What is respiration?
2 forms of nitrogen
What are nitrates and nitrites?
What is an ecosystem?
Competition between members of the same species
What is intraspecific competition?
A defense mechanism used by organisms to disguise their appearance
What is camouflage?
What is photosynthesis?
This process creates ammonia from decaying organic matter
What is ammonification?
What is a habitat?
These organisms can only eat plants because these are the things they have the enzymes to digest
What are Herbivores?
Competition between organisms of different species
What is intraspecific competition?
This process produces the most carbon dioxide that is later mostly found in the atmosphere
What is combustion?
Without these organisms, most of the nitrogen would not be in a usable form
What are nitrogen fixing bacteria?
Populations cannot continue to grow and grow exponentially due to these
What are limiting factors?
What is mutualism?
These organisms can digest both plants and animals
What are omnivores?
These things break down the carbon compounds found in dead organisms
Consumers obtain nitrates by eating plants. Plants absorb nitrates by doing this process
What is assimilation?
What is the biosphere?
How an organism uses its abiotic and biotic factors in its ecosystem
What is a niche?
A bird making a nest in a tree is an example of this type of relationship
What is commensalism?
This is the largest carbon sink or storage area on the planet
What is the ocean?
When excess fertilizers are used, extra nitrates get into the water system and cause this problem
What is eutrophication?
What is Natural Selection?
Organisms that do this alter their behaviors so they can live together
What is species coexistence?
This type of relationship will harm you, but it won't kill you
What is parasitism?
