When a mouse is eaten by a predator (for the mouse) - Correct- A, B, D biotic-living abiotic-nonliving abiotic factor ex- When a plant's growth is limited by the high acidity of the soil (for the plant) Which of the following are examples of trophic interactions?

(mouse is eaten by a predator: mouse primary productivity- secondary production= consumer) flow of energy. Which of the following are consumer-resource interactions? Focus on the organisms described, not other organisms you may imagine being present. Choose all that apply. At least one is correct. A. When a mouse is eaten by a predator B. When a human provides a home to 10^11 bacteria in their gut C. When a plant in the forest is outcompeted by a more shade-tolerant species. D. When a plant's growth is limited by the high acidity of the soil - A. Consumer resource interaction: Organisms get their nutrition by eating other living organisms. The consumer benefits while the consumed organism (the resource) loses These are called "trophic" interactions Include predation, herbivory, and parasitism. ex. keystone predator=wolf
