Which of the following organisms are not classified as consumers?

2-4

10-12
Explanation / Answer
1. In general, the more narrow a species’ habitat tolerance the larger the range of that species.
Answer: True
2. What would you say is the optimal pH for radish growth?
Answer:
PH 2-4: The weaker the plants will be in terms of germination and plant height.
PH 4-6: Average growth
PH 6-8: Grow well
PH 10-12: Plant growth will be delayed, but not inhibited altogether.
3. In the northeastern US, acid rain has historically been a problem. Based on this, what would you predict would happen if acid rain continues?
Answer: All the given answers are correct
If acid rains continue the plant vegetation would be disappeared.
4. Which of the following organisms are not classified as consumers?
Answer: Trees
Trees are autotrophs, which synthesise their own food material by photosynthesis, hence they are not considered as consumers.
