Which statement best describes the flow of energy between an ant and an antlion in an ecosystem?
A
The antlion transfers energy to the ant by decomposing organic matter.
B
The antlion acts as a predator, obtaining energy by consuming the ant.
C
The ant provides energy to the antlion by photosynthesis.
D
The ant and antlion share energy equally through mutualistic interactions.
검증된 단계별 안내1
Understand the roles of organisms in an ecosystem: In this case, the ant and the antlion are part of a food chain. The antlion is a predator, and the ant is its prey. Predators obtain energy by consuming other organisms.
Eliminate incorrect options: The ant does not perform photosynthesis because it is not a producer (plants and some algae perform photosynthesis). Therefore, the statement about the ant providing energy to the antlion by photosynthesis is incorrect.
Analyze the role of decomposition: Decomposers break down organic matter into simpler substances, recycling nutrients back into the ecosystem. However, the antlion is not a decomposer; it is a predator. Thus, the statement about the antlion transferring energy to the ant by decomposing organic matter is incorrect.
Evaluate mutualistic interactions: Mutualism is a relationship where both organisms benefit. The ant and the antlion do not share energy equally or benefit mutually; the antlion consumes the ant for energy. Therefore, the statement about mutualistic interactions is incorrect.
Conclude the correct answer: The antlion acts as a predator, obtaining energy by consuming the ant. This accurately describes the flow of energy between the two organisms in the ecosystem.
