what is the most likely effect of deforestation that results from urbanization of an area?
2 points
a) trees will be replaced quickly but by different tree species.
b) there will be less land available for agriculture.
c) there will be an increase in biodiversity.
d) soil erosion will increase.

a marine ecosystem off the california coast consists of leatherback turtles that feed on jellyfish, and killer whales that prey on the leatherback turtles. habitat loss and fishing have been identified as the main reasons for the reduced numbers of leatherback turtles, who are on the verge of being declared an endangered species.

Explanation:

First Question (about ecological succession, though the options are given with B selected, but let's focus on the second question about deforestation effect)

Second Question (Deforestation from urbanization effect):

• Option A: Deforestation from urbanization (converting land to urban use) doesn't quickly replace trees with different species; urbanization typically replaces forests with non - forested urban infrastructure.
• Option B: Urbanization for deforestation is about converting land to urban use, not directly reducing agricultural land (in fact, it might be a shift from forest to urban, not necessarily reducing agri land in a direct causal way for this context).
• Option C: Deforestation reduces habitats, so biodiversity is likely to decrease, not increase.
• Option D: Trees help hold soil with their roots. When deforestation occurs (due to urbanization), the root systems that prevent soil erosion are removed, so soil erosion will increase.

Answer:

D) Soil erosion will increase.
