Energy in an Ecosystem Review- LS

Front

Arrow in food chain points to:

Back

Organism that gets the energy

Answer explanation

In a food chain, the arrow indicates the direction of energy flow. It points to the organism that gets the energy from the previous one, highlighting the transfer of energy through the ecosystem.

Front

Energy source from mouse

Back

fox

Answer explanation

The fox is a carnivorous predator that hunts and consumes mice for energy, making it the organism that gets energy from the mouse. The cricket and grass are not predators, and the Sun provides energy indirectly.

Front

Energy source for snake

Back

Eating the rabbit

Answer explanation

The snake gets energy by eating the rabbit, which is a primary consumer in the food chain. The rabbit feeds on plants, transferring energy from the plants to the snake when it is consumed.

Front

Energy source from nonliving thing

Back

the grass

Answer explanation

The grass gets energy from the Sun, a nonliving thing, through photosynthesis. In contrast, the mouse and the fox obtain energy by consuming living organisms.

Front

Energy flow in food chain

Back

Bird gets energy from caterpillar

Answer explanation

The correct choice is that the bird gets energy from the caterpillar. In a food chain, energy flows from one organism to another, and here, the bird consumes the caterpillar, obtaining energy from it.

Front

Animal that hunts and eats others

Back

Predator

Answer explanation

An animal that hunts and eats other animals is called a predator. Predators play a crucial role in the ecosystem by controlling the population of prey species.

Front

Animal hunted for food

Back

Answer explanation

An animal that is hunted and eaten for food is referred to as 'prey'. In ecological terms, prey are the species that predators hunt for sustenance.

Front

All organisms need _______________

Back

energy

Answer explanation

All organisms need energy to survive, as it is essential for growth, reproduction, and maintaining bodily functions. Unlike ears, eyes, or bones, energy is a fundamental requirement for all life forms.

Front

Producer in food chain

Back

Tree

Answer explanation

In a food chain, the producer is the organism that creates energy through photosynthesis. The tree, as a plant, converts sunlight into energy, making it the producer. The sun provides energy, but it is not an organism.

Front

Food Chain

Back

Path of energy in an environment

Answer explanation

A food chain illustrates the path of energy as it flows through an ecosystem, showing how organisms are interconnected through feeding relationships. This makes 'the path of energy in an environment' the correct choice.
