A response to a change that increases the change in conditions. It reinforces the initial change.

Increased algal blooms due to pollutants from runoff, harming the food chain

Increased algae population blocking sunlight for plants

Non-native species competing with native species for resources

A response to change that reduces the change, returning conditions to a previous state. It balances the change.

The maximum population size an environment can support based on resources.

How members of an aquatic community interact and change over time.

All living organisms in a particular aquatic environment that interact with each other.

Not enough food, water, shelter, or mates impacting population size

Excessive rainfall leads to water levels exceeding the capacity of bodies of water.

Insufficient rainfall for a long period leads to water loss from soil and bodies of water.

Increased pollution, warming oceans, and lower pH cause coral population decline.

Introduction of species without natural predators leads to population explosion.

Polluted bodies of water lead to a decline in the ecosystem's health.

Changes in water temperature cause die-off of organisms not adapted to new conditions.

Introduction of pollutants to a body of water increases algal blooms.

Cold winters cause some birds to move to warmer climates.

Fish lay eggs for spawning when seasonal conditions are right.

Heavy rainfall washes away aquatic plants.

Rapid population increase, often with no natural predators.

Areas of low to no oxygen in water, harming aquatic life.

Changes in water temperature affect aquatic organisms' rates and life.

Pollution from a specific location, like a pipe.

Pollution spread from many sources, such as runoff.
