After a volcanic eruption, this type of succession occurs.
What is primary succession?
This organelle carries out photosynthesis.
What is the chloroplast?
Beak shape in birds is this type of adaptation.
What is a structural adaptation?
As energy moves up trophic levels, this happens to the amount of available energy.
This type of reproduction produces identical offspring.
What is asexual reproduction?
After a forest fire, this type of succession occurs.
What is secondary succession?
This organelle stores water and helps maintain pressure in plant cells, supporting their structure.
What is the vacuole?
When individuals with beneficial traits survive and reproduce more often, this process is occurring.
What is natural selection?
This is the group at the base of the energy pyramid.
What are producers?
This type of reproduction increases genetic variation.
What is sexual reproduction?
Lichens and mosses are examples of this type of group.
What are pioneer species?
If these structures stopped functioning, the cell could no longer build proteins needed for growth and repair.
What are ribosomes?
Migration is an example of this type of adaptation.
What is a behavioral adaptation?
This is the term for the total mass of living organic matter in a given area or trophic level.
What is biomass?
These structures contain genes that determine inherited traits.
What are chromosomes?
This is the term for the stable, final stage of an ecosystem that forms after succession is complete.
What is a climax community?
This is the name and function of the organelle labeled 2.

What is the mitochondria and energy production.
This is the term for differences in traits among individuals.
What is variation?
This explains why only a small percentage of energy is passed from one trophic level to the next.
What is the 10% rule - energy is lost as heat?
These are segments of DNA that code for specific traits.
What are genes?
This concept describes how several different species in an ecosystem perform the same role.
What is functional redundancy?
This is the name and function of the organelle labeled 12.

What is the cell wall and structure/function/defense from pathogens?
A species with little variation is exposed to a sudden environmental change.
This predicts what will most likely happen to the population.
What is the population may decrease or go extinct?
This type of organism converts sunlight into chemical energy and provides energy for all other trophic levels (hint: producers)
What is an autotroph?
If genes are changed or mutated, this will most likely be affected in the organism.
What are traits?
