Question

Secondary consumers would eat which one following? A. Producers B. Plants C. Herbivores D. Carnivores E. Tertiary consumers

Short answer

C. Herbivores

Step-by-step solution

Understanding the Food Chain

The food chain is a series of organisms each dependent on the next as a source of food. It starts with producers (plants) and moves up to various levels of consumers.

Identify Producers

Producers are organisms that can make their own energy through biochemical processes, like photosynthesis. Example: Plants.

Identify Primary Consumers

Primary consumers feed on producers. They are herbivores or plant-eaters. Example: Many insects, deer.

Identify Secondary Consumers

Secondary consumers feed on primary consumers. They are typically carnivores or omnivores. Example: Birds that eat insects.

Identify Tertiary Consumers

Tertiary consumers feed on secondary consumers. They are typically top predators in their environment. Example: Eagles, large fish.

Find Correct Answer

Secondary consumers eat primary consumers, which are herbivores. Therefore, the correct answer is C. Herbivores.

Key concepts

Secondary Consumers

To understand secondary consumers, it's important to look at their place in the food chain. These animals primarily feed on primary consumers, which are often herbivores. This makes secondary consumers carnivores or omnivores. For example, a bird that eats insects is a secondary consumer. They play a crucial role by controlling the population of herbivores, ensuring the ecosystem remains balanced.

Herbivores

Herbivores are animals that eat plants. They are known as primary consumers because they directly consume producers (plants). Examples of herbivores include rabbits, deer, and many insect species. These animals are the second link in the food chain, following producers. By feeding on plants, herbivores convert the energy stored in plants into a form that can be used by predators.

Trophic Levels

Trophic levels refer to the hierarchical positions in a food chain. Each step in the chain is a different level. For example:

• Producers (plants) make up the first trophic level.
• Herbivores or primary consumers make up the second trophic level.
• Secondary consumers, which eat herbivores, are on the third trophic level.
• Tertiary consumers, which consume secondary consumers, are on the fourth trophic level.

Each level represents a step in the transfer of energy and nutrients through an ecosystem.

Carnivores

Carnivores are animals that eat other animals. They can be secondary or tertiary consumers in the food chain. For instance, a lion eating a deer (secondary consumer) or a shark eating a smaller fish (tertiary consumer). Carnivores are essential for keeping the populations of other species in check, providing stability in ecosystems. They usually have specialized adaptations for hunting and consuming prey, such as sharp teeth and claws.

Primary Consumers

Primary consumers are the first level of consumers in the food chain. They are herbivores that feed on plants, which are the producers. Examples include cows, caterpillars, and giraffes. By consuming plants, primary consumers play a significant role in transferring energy from plants to higher trophic levels. They help in the breakdown of plant material, aiding in the cycling of nutrients within an ecosystem.
