Using the following organisms, construct a grassland food chain (remember to begin with energy from the sun): grass, toads, ladybugs (carnivorous beetles), aphids (small grazing insects), and snakes. (energy from sun), aphids, grass, ladybugs, toads, snakes
(energy from sun), grass, aphids, ladybugs, toads, snakes
(energy from sun), grass, ladybugs, aphids, toads, snakes
(energy from sun), grass, aphids, ladybugs, snakes, toads

Option B

Explanation:

The food chain is as follows -

grass -> aphids (small grazing insects)  -> ladybugs (carnivorous beetles) -> toads  -> snakes

The grass is the primary producer while the snake is the tertiary consumer.

Grass is consumed by grazing insects, which is then consumed by carnivorous beetles. Carnivorous beetles is eaten by toads which is turn is fed upon by snake.

Hence, option B is correct
