Parasite/Host
About this % of energy transfers upward.
10%
Role an organism plays in an ecosystem
Niche
Warm water causes dissolved oxygen to do this.
Decrease
Water availability affecting population size is called this.
Limiting factor
Organisms that recycle nutrients.
Decomposers
Organisms at top trophic levels have the ___ energy.
Least
Maximum population an ecosystem can support.
Carrying capacity
Human activity increasing atmospheric CO₂
Industrialization
Forest fire followed by regrowth is this process.
Secondary succession
If small invertebrates decrease, crayfish will likely do this.
Decrease
Toxins become most concentrated at this trophic level.
Top predators
Gradual ecosystem change over time.
Succession
Mulching lawnmowers help this process
