You are planning a dive in a lake, and are eager to watch underwater organisms both close up and far away...?

Question

These are 3 tricky biology questions I can't find the answer to, it can be this or that, so please help me, no guessing. Thank you..Have a great day.

1. You are planning a dive in a lake, and are eager to watch underwater organisms both close up and far away. You would do well to choose

A) a nutrient-poor lake.

B) a nutrient-rich lake.

C) a relatively deep lake.

D) A and C

E) B and C

2. You are interested in studying how organisms react to a gradient of abiotic conditions and how they coexists in this gradient. The best biome in which to conduct such a study is

A) mountains.

B) an intertidal zone.

C) a river.

D) tropical forest.

E) an eutrophic lake.

3. As climate changes because of global warming, species' ranges in the northern hemisphere may move northward. The trees are most likely to avoid extinction in such an environment are those that

A) have wind-dispersed seeds.

B) have animal-dispersed seeds.

C) produce well-provisioned seeds.

D) A and B

E) A, B, and C

Answer 1

1. You are planning a dive in a lake, and are eager to watch underwater organisms both close up and far away. You would do well to choose

E) B and C

A deep nutrient-rich lake would allow a diverse ecology of organisms to thrive.

2. You are interested in studying how organisms react to a gradient of abiotic conditions and how they coexists in this gradient. The best biome in which to conduct such a study is

A) mountains.

High altitude mountains would provide the best abiotic condition.  Living organism thrives in the other ecosystems.

3. As climate changes because of global warming, species' ranges in the northern hemisphere may move northward. The trees are most likely to avoid extinction in such an environment are those that

E) A, B, and C

This is subjective because it isn't how the seed is dispersed or grown but how the tree itself will survive in various environments.  Some trees may have well dispersed seeds but can only grown in limited regions.

Answer 2

1 E

2 A

3 D

I'm pretty sure these are right, hope this helps.  Good Luck!
