Explain this statement: “The greenhouse effect is a good thing, but global warming is too much of a good thing.”
The greenhouse effect is good because it keeps the earth from being too cold for life. Global warming is an enhancement of the greenhouse effect that causes the earth to get too warm.
What do nitrogen-fixing bacteria provide to other organisms?
they provide nitrogen to producers
Name the five invertebrate phylum with an organism for each.

What do sponges eat and how do they get their food?
they eat algae by pumping water through their bodies and capturing the food from the water
What function does the cuticle perform in an earthworm?
it helps in respiration
What is the common mode of asexual production for organisms of phylum Cnidaria? What is the common mode of asexual production for those in phylum Platyhelminthes?
budding for Cnidaria, regeneration for Platyhelminthes
What are the common characteristics for phylum Arthropoda?
exoskeleton, body segmentation, jointed appendages, ventral nervous system, open circulatory system
Why do arthropods molt?
their growing bodies get too large for their exoskeletons
