The algae and the crustacean both transfer energy to each other.
Energy is transferred from the crustacean to the algae.
Energy is transferred from the algae to the crustacean.
Energy is not transferred between the algae and the crustacean
Energy is transferred from the algae to the crustacean.
To determine which of the options is a producer in the food web, we need to understand the roles of the organisms involved. In a food web, producers are organisms that can produce their own food through a process called photosynthesis. They convert sunlight into energy and are usually plants or other autotrophic organisms.
Let's examine the options given:
1. Ant: Ants are consumers, not producers. They obtain their energy by consuming other organisms or organic matter.
2. Tadpole: Tadpoles are also consumers, as they rely on external food sources for their energy.
3. Sunlight: Sunlight is not an organism and cannot be classified as a producer or a consumer. It provides the energy needed for photosynthesis, which is vital for producers.
4. Grass: Grass is a classic example of a producer. It has the ability to undergo photosynthesis and produce its own food using sunlight, water, and nutrients from the soil.
Therefore, out of the options presented, the producer in the food web is "grass." It serves as the foundation of the ecosystem by providing energy for other organisms.
