Ecosystems in human-dominated landscapes are generally and , and support more species with - selected reproductive strategies, and are typical of succession.

Group of answer choices

The correct answer is number 3. fragmented, disturbed, r, early.

Ecosystems in human-dominated landscapes are generally fragmented and disturbed, and support more species with r - selected reproductive strategies, and are typical of early succession.

Explanation:

Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.

r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.

As human-dominated landscapes are generally fragmented and disturbed, new areas are constantly available for r species to colonize them. This is an early stage of succession when these r species arrive in the open perturbated space and colonize it. These r species start a modification in the habitat that makes it suitable for the posterior establishment of later K species. As conditions get better, competition becomes more frequently between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
