Consider this northern site of primary succession following the retreat of a glacier. plant species at location b. would eventually change to the species seen at location c. because of what factor? a) being shaded out by taller species b) competition for water resources c) competition for root space d) pathogens and disease

The answer is A, being shaded out by taller trees.

Explanation:

Low growing shrubs and small trees eventually give way to larger tree species. Notice there is little under story (lower level) because of light restrictions.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

the answers are a and c
