Question 2
What is the difference between net primary productivity (NPP) and gross primary productivity (GPP)?(1 point)
Responses

NPP is the total amount of energy captured by plants, and GPP is the energy available to consumers
NPP is the total amount of energy captured by plants, and GPP is the energy available to consumers

GPP is the rate of decomposition in an ecosystem, whereas NPP is the energy captured by plants
GPP is the rate of decomposition in an ecosystem, whereas NPP is the energy captured by plants

Both NPP and GPP refer to the energy used by plants, there is no difference

Answer 1

Here are the correct answers to each of your questions based on ecological principles:

**Question 1: What is the difference between producers and consumers?**
- **Correct Answer:** Producers create their own food through photosynthesis or chemosynthesis, while consumers obtain energy by eating other organisms.

**Question 2: What is the difference between net primary productivity (NPP) and gross primary productivity (GPP)?**
- **Correct Answer:** Net primary productivity (NPP) considers energy used in respiration, while gross primary productivity (GPP) does not.

**Question 3: Compared to the amount of energy available at the bottom of a food chain, what typically happens to the amount of energy available at higher trophic levels?**
- **Correct Answer:** The amount of energy decreases.

**Question 4: Select the response that best explains why detritivores are important for maintaining the health of an ecosystem.**
- **Correct Answer:** Detritivores decompose dead organic matter, recycling nutrients back into the ecosystem.

**Question 5: Which of the following organisms perform photosynthesis?**
- *[Please provide the options for this question so I can help you answer it.]*

**Question 6: How can biomass be used as a source of energy?**
- **Correct Answer:** Biomass can be directly burned or converted into biofuels like ethanol and biogas, which can then be burned to release energy.

**Question 7: What role do decomposers play in a food web?**
- **Correct Answer:** They break down organisms and recycle nutrients.

**Question 8: In a food web, what would likely happen if a top predator is removed?**
- **Correct Answer:** The number of herbivores would increase.

**Question 9: Invasive species are a threat to ecosystems because they:**
- **Correct Answer:** Do not have a natural predator.
