Praticing Food Chains

What type of diagram shows a linear (In a line) sequence of how energy and nutrients flow from one organism to another in an ecosystem.

• Food Chain

• Food Web

• Energy Pyramid

• Organism Chart

Answer explanation

A Food Chain illustrates a linear sequence of energy and nutrient flow from one organism to another in an ecosystem, showing how each organism is connected in a direct line of consumption.

What is an omnivore?

• an animal that only eats other animals

• an animal that eats plants only

• an animal that eats both plants and animals

• an animal that absorbs energy from the sun

Answer explanation

An omnivore is defined as an animal that eats both plants and animals. This distinguishes them from herbivores, which eat only plants, and carnivores, which eat only other animals.

What is a carnivore?

• An animals that eats plants only

• An animals that only eats other animals

• An animals that eats both plants and animals

• An animals that absorbs energy from the sun

Answer explanation

A carnivore is defined as an animal that primarily eats other animals. This distinguishes it from herbivores, which eat plants, and omnivores, which consume both plants and animals.

What are plants called in a food chain?

• Producers

• Consumers

• Decomposers

• Scavengers

Answer explanation

In a food chain, plants are called producers because they create their own food through photosynthesis, forming the base of the food chain. They provide energy for consumers, which are the next level in the chain.

True/False
Food webs show you everything an animal eats. Food chains show you one thing.

• True

• False

Answer explanation

True. Food webs illustrate all the organisms an animal consumes, showing the complex interactions in an ecosystem, while food chains depict a linear sequence of one organism eating another.

Which is the correct food chain order?

• Plant-->Primary Consumer--> Secondary Consumer 

• Plant <-- Primary Consumer <-- Secondary Consumer

• Secondary consumer -->Primary Consumer  --> Plant

• Primary Consumer --> Secondary consumer --> Plant

Answer explanation

The correct food chain order is Plant -> Primary Consumer -> Secondary Consumer. This sequence illustrates how energy flows from producers (plants) to herbivores (primary consumers) and then to carnivores (secondary consumers).

Look at the food chain. How do foxes get energy?

• from eating rabbits

• from eating grass

• from the sun

• from eating other foxes

Answer explanation

Foxes get energy by consuming other animals, primarily rabbits. This is because they are carnivores and rely on the energy stored in the bodies of their prey, rather than from plants or other sources.

True or False? Herbivores can only eat plants

• True

• False

Answer explanation

True. Herbivores are animals that primarily consume plants, including leaves, fruits, and vegetables. They do not eat meat, which distinguishes them from carnivores and omnivores.

Select all that apply: How do producers get their energy and what is their job in the ecosystem?

• Makes their own food using the sun

• Eats other organisms for food

• Makes energy available from the sun to the rest of the ecosystem

• Takes energy from other organisms and passes it to the rest of the ecosystem

Answer explanation

Producers, like plants, make their own food using sunlight through photosynthesis. This process not only sustains them but also makes energy available to other organisms in the ecosystem.

What is the role of decomposers in the ecosystem?

• Makes their own food through photosynthesis

• Acts as the primary source of energy for all food chains

• Break down dead organisms and waste, returning nutrients to the soil

Answer explanation

Decomposers play a crucial role in ecosystems by breaking down dead organisms and waste. This process returns essential nutrients to the soil, promoting plant growth and maintaining the balance of the ecosystem.
