b urbanization and industrialization
c geographical isolation
d increased pollution levels
6 what is one of the human - induced impacts altering biogeochemical cycles?
a reduced pollution levels
b controlled industrial emissions
c climate change effects
d increased forest conservation
7 a herd of elephants staying together in a given habitat demonstrates which type of dispersion pattern?
a uniform
b clumped/ clustered
c random
d linear

Explanation:

1. Exponential growth shows unrestricted increase over time, forming a J-shaped curve.
2. An apple orchard with evenly spaced trees has a uniform dispersion pattern.
3. Sustainable practices aim to use resources without depleting biodiversity.
4. Cyclic population fluctuations between moose and wolves are characteristic of a predator-prey relationship.
5. Geographical isolation allows unique species evolution, increasing biodiversity.
6. Human activities like fossil fuel burning disrupt biogeochemical cycles, contributing to climate change.
7. A herd of elephants staying together shows a clumped dispersion pattern (individuals grouped).

Answer:

1. d. Exponential growth
2. d. Uniform
3. b. Resource use without depleting biodiversity
4. b. Predator-prey relationship
5. c. Geographical isolation
6. c. Climate change effects
7. (Assuming option d is "Clumped" as the visible pattern for social animals) d. Clumped
