Why are a variety of instruments needed to measure change in the climate system?
a. A different type of instrument is needed for each different climate.
b. The climate system involves a number of different factors that are measured differently.
Climate is determined over a number of years, rather than a short period of time.
d. Different areas have developed different instruments to measure climate change.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

d. planting trees

the trees take in carbon to make oxygen.
