Answer 1

Sure! Here are the correct answers based on your questions:

Question 1: The process that converts solar energy into chemical energy in an ecosystem is:

• Photosynthesis

Question 2: The term that describes organisms that produce their own food using sunlight is:

• Autotrophs

Question 3: An example of a primary consumer from the trophic pyramid is:

• Organisms in section B (assuming section B represents primary consumers)

Question 4: The role decomposers play in the cycle of matter is:

• They break down dead organisms, returning nutrients to the soil

Question 5: The correct order of trophic levels from bottom to top is:

• Producers, primary consumers, secondary consumers, tertiary consumers

Question 6: The role of the mushroom in the food web is:

• Decomposer

Question 7: Based on the food web, where does the energy go after the hawk?

• Bacteria (assuming bacteria are associated with decomposition, which would follow predators)

Question 8: From the food web, the secondary consumer is:

• Snake (assuming snake is the second consumer after primary consumers)

Question 9: The term that describes organisms that feed on both plants and animals is:

• Omnivores

Question 10: The trophic level that typically has the least amount of energy available is:

• Tertiary consumers

Question 11: The correct statement that states the 10% rule in ecology is:

• Only 10% of the energy at one trophic level is transferred to the next trophic level

Question 12: In an energy pyramid, the level that typically has the most biomass is:

• Producers

Question 13: Primary productivity is:

• The rate at which energy is stored by plants

Question 14: Biomagnification refers to:

• The increase in toxin concentration as it moves up the food chain

Question 15: DDT is an example of a substance that biomagnifies. It was historically used as:

• a pesticide

Question 16: Anaerobic respiration occurs in the absence of:

• oxygen

Question 17: Matching the organism with its role in the ecosystem:

• Grass: Producer
• Mushroom: Decomposer
• Snake: Tertiary Consumer
• Rabbit: Primary Consumer
• Sun: Energy Source

Question 18: (Answer this in your own words.) Here’s a guideline for a possible response: If a primary consumer is removed from an ecosystem, it can lead to overpopulation of the primary producers, as there would be fewer herbivores to feed on the plants. This could result in a depletion of resources, creating competition among remaining species. Additionally, secondary consumers that rely on primary consumers for food may decline in number due to the lack of their food source, disrupting the entire food web and harming biodiversity.

Please provide your own thoughts for Question 18, as I cannot generate responses on your behalf.
