What are Decomposers?

300

an ecological interaction where both species involved benefit, often enhancing survival, reproduction, or fitness.  ex:pollinators

What is mutualism?

the theory that changes in the Earth's crust during history have resulted from the action of continuous and uniform process.  Geological processes that occur today have also occurred in the past.

help fight bacterial infections like strep throat

What is an antibiotic?

400

association between two organisms in which one benefits and the other derives neither benefit nor harm.  ex: a bird building a nest inside a dead tree

What is commensalism?

400

matter can neither be created or destroyed by physical or chemical changes, it can only change form.

What is the Law of Conservation of Matter?

500

Excessive amounts of Nitrates and phosphates enter a body of water through runoff.  Because of this there is an increase in algae blooms which decreases dissolved oxygen levels

Single celled, prokaryotic.  Can live in a variety of climates.  Most are good, but some can cause harm, they are living, and antibiotics and be used to treat.

What is bacteria?
