Question

present, the grasses and flowers of succession will happen. with the and nutrient - rich, so the stages of succession will happen. with the and shrubs return to the area, soon followed by young trees. with the growth of the plants, the animals will come back as well, and the ecosystem is on its way to achieving a climax community. using the reading passage, answer the following questions: 1. what is ecological succession? 2. what is the difference between primary and secondary succession? 3. what is a pioneer species? what are some examples? 4. when the grass and flowers begin to grow, what organism also inhabits the area? 5. what is a primary consumer?

Explanation:

1. Ecological succession is the process by which the structure of a biological community evolves over time. As described in the passage, it involves the return of plants (grasses, flowers, shrubs, young trees) and the subsequent return of animals as the ecosystem moves towards a climax community.
2. Primary succession occurs in an area where no previous community existed, starting from bare rock or a new - formed land. Secondary succession occurs in an area where a community previously existed but was disturbed, like the area described where plants and animals return after some event.
3. A pioneer species is the first species to colonize a barren or disturbed area. Examples include lichens and mosses in primary succession, and grasses and wildflowers in secondary succession as mentioned in the passage.
4. When grass and flowers begin to grow, small herbivorous animals such as insects, rabbits, and rodents also inhabit the area as they feed on these plants.
5. A primary consumer is an organism that feeds on primary producers (plants). They are herbivores in a food chain.

Answer:

1. The process by which the structure of a biological community evolves over time, with plants returning first and animals following as the ecosystem moves towards a climax community.
2. Primary succession starts in an area with no previous community (e.g., bare rock), while secondary succession occurs in an area where a community previously existed but was disturbed.
3. A pioneer species is the first to colonize a barren or disturbed area. Examples: lichens, mosses (primary succession); grasses, wildflowers (secondary succession).
4. Small herbivorous animals like insects, rabbits, and rodents.
5. An organism that feeds on primary producers (plants), i.e., a herbivore in a food - chain.
