Question 1 A)Consider what you know about biotic and abiotic factors in an ecosystem. What is one of the reasons that nutrients in a vegetable patch might be considered abiotic?(1 point) Responses Nutrients are mostly obtained from the soil. Nutrients are mostly obtained from the soil. Nutrients can come from dead plants which have decomposed. Nutrients can come from dead plants which have decomposed. Nutrient levels can change with changing ecosystems. Nutrient levels can change with changing ecosystems. Available nutrients affect the carrying capacity of garden plants. Available nutrients affect the carrying capacity of garden plants. Question 2 A)Of the following factors that impact biodiversity, which one would be considered a micro-effect?(1 point) Responses A stand of aspen trees dies and decays, leaving a clearing in the forest.

A forest is cleared for the construction of a suburban home division. A forest is cleared for the construction of a suburban home division. An invasive species of plant is introduced that outcompetes all local plants. An invasive species of plant is introduced that outcompetes all local plants. Question 3 A)Why does ecology need to study the biotic and abiotic elements?(1 point) Responses It is studying a population. It is studying a population. It is studying the ecosystem. It is studying the ecosystem. It is studying the community. It is studying the community. It is studying a species. It is studying a species. Question 4 A) The brown tree snake is an invasive species in the island of Guam. The brown tree snake feeds mainly on birds and other animals' eggs (birds and reptiles). The rapid increase of brown tree snakes has caused the extinction of several bird species. These birds mainly fed on insects. The brown tree snake does not have a natural predator. Which of the following is an impact that the brown tree snake has on the ecosystem in Guam? (1 point) Responses The small plant population will increase drastically.

Answer 1

Question 1:

- One of the reasons that nutrients in a vegetable patch might be considered abiotic is that they are mostly obtained from the soil.

Question 2:
- Of the following factors that impact biodiversity, a micro-effect would be when a stand of aspen trees dies and decays, leaving a clearing in the forest.

Question 3:
- Ecology needs to study the biotic and abiotic elements in order to study the ecosystem.

Question 4:
- An impact that the brown tree snake has on the ecosystem in Guam is that the bird population, which fed on insects, has decreased drastically.

Question 5:
- The difference between small, controlled lab experiments and ecosystem-scale experiments include the applicability of the results to real-world scenarios and the number of variables considered.
