Food Chain, Food Web, and Life Cycle

What is a producer in a food chain?

• An organism that produces its own food through photosynthesis.

• An organism that lives in a symbiotic relationship with another organism.

• An organism that consumes other organisms for food.

• An organism that breaks down dead organic matter.

Explain the role of decomposers in an ecosystem.

• Decomposers reduce the amount of oxygen in the ecosystem.

• Decomposers primarily feed on live organisms in the ecosystem.

• Decomposers create new organisms in the ecosystem.

• Decomposers break down dead organisms and organic matter, releasing nutrients back into the ecosystem.

Define a food chain and provide an example.

• A food chain is a series of organisms where each organism eats the one below it in the chain. For example, grass is eaten by a grasshopper, which is then eaten by a frog, which is eaten by a snake, and so on.

• A food chain is a series of restaurants where each restaurant serves a different type of cuisine.

• A food chain is a series of grocery stores where each store sells different brands of food.

• A food chain is a series of animals where each animal is connected by a physical chain.

How is a food web different from a food chain?

• A food web is a linear sequence of organisms, unlike a food chain.

• A food web always starts with a predator, unlike a food chain.

• A food web is more complex and interconnected compared to a food chain.

• A food web consists of only producers and consumers, unlike a food chain.

Describe the life cycle of a butterfly.

• Butterflies are born as adults and do not go through different stages.

• The life cycle of a butterfly consists of three stages: egg, pupa, and adult.

• The life cycle of a butterfly includes five stages: egg, larva, pupa, adult, and elder.

• The life cycle of a butterfly consists of four stages: egg, larva, pupa, and adult.

Why are decomposers important in maintaining balance in an ecosystem?

• Decomposers are important in maintaining balance in an ecosystem because they recycle nutrients by breaking down dead organisms and waste.

• Decomposers are important in maintaining balance in an ecosystem because they harm other organisms

• Decomposers are important in maintaining balance in an ecosystem because they disrupt the food chain

• Decomposers are important in maintaining balance in an ecosystem because they create pollution

Explain the concept of energy flow in a food chain.

• Energy flow in a food chain involves the transfer of energy from one organism to another through consumption, starting with producers and moving through various trophic levels.

• Energy flow in a food chain is solely dependent on abiotic factors.

• Energy flow in a food chain involves the exchange of genetic material between different species.

• Energy flow in a food chain refers to the movement of physical objects between organisms.
