An organism that can be a primary, secondary, or tertiary consumer in different food chains is this
What is an omnivore
300
The arrows in a food chain show this
What is the movement of energy

These help get nitrogen from the air into a form plants can use
What are bacteria

Planting trees in a buffer zone around streams helps prevent these two different types of pollution
What are sediments and nutrients (Nitrogen and Phosphorus)

What is the independent variable
400
All consumers are also this

A scientists plants 4 plants to test if amount of sugar dissolved in water will cause plants to increase in height. One is watered with water that has 2 mg of sugar dissolved. the second has water with 4 mg of sugar. The third is water with water that has 8 mg of sugar. the fourth is water with water that has 10 mg of sugar. There is a fifth plant as a control. This is what happens to it.
What is it is water it with water that has no added sugar.
500

These are two ways plants participate in the water cycle.
What is transpiration and taking in groundwater
500
The reason fertilizers cause algal blooms
What is they contain nitrogen and phosphorus which are limiting nutrients. With increased levels of limiting nutrients producers become more productive.
