A forest has a large variety of trees, shrubs, herbs, insects, birds, and mammals living together. This variety of living organisms in the forest is an example of:
Q4 · Environment and Ecosystem · MEDIUM
In a pond ecosystem, the number of organisms at each trophic level can be represented as a pyramid. If there are 10,000 units of energy available at the producer level, approximately how much energy will be available to secondary consumers, assuming the 10% law of energy transfer?
Q5 · Environment and Ecosystem · HARD
In a certain region, a large number of frogs were killed to use their legs as food. After some time, farmers in that region noticed a significant increase in crop damage by insects. What ecological principle does this situation best illustrate?
