Food and Feeding Habits of Animals

Why do omnivores rarely go hungry?

• Because they can eat both plants and animals.

• Because they only eat plants.

• Because they only eat animals.

Which food chain is in the correct order?

• grass-> grass hopper-> frog-> snake

• grass-> frog-> snake-> grass hopper

Which of the following best describes a food chain?

• 
  A circular pattern indicating the recycling of nutrients

• A random arrangement of organisms in an ecosystem

• A linear sequence showing the flow of energy from producers to consumers

• 
  A network of plants competing for sunlight

During a biology class, Henry was curious about the eating habits of different animals. He asked, 'What is the difference between gnawing and cud chewing?'

• Gnawing is chewing food with flat teeth, while cud chewing is chewing food with sharp teeth.

• Gnawing is swallowing food without chewing, while cud chewing is chewing food thoroughly before swallowing.

• Gnawing is chewing plants only, while cud chewing is chewing meat only.

• Gnawing is chewing food repeatedly with sharp teeth, while cud chewing is bringing back swallowed food to chew it again.

Grace and Michael were discussing why omnivores have a combination of teeth. Why do you think that is?

• To chew food quickly so they can eat more.

• To allow them to eat both plant-based and animal-based food.

• To grow stronger teeth over time.

Elijah and Ava were exploring a garden when they learned that green plants are the starting points of all food chains. Can you explain why this is the case?

The animals that eat both plants and other animals are called

What happens if one part of the food chain is removed or disrupted, like if bees in a garden disappear?

• Nothing happens; the food chain continues without any changes.

• The food chain becomes stronger as fewer animals and plants compete for resources.

• Plants that depend on bees for pollination may not grow, and animals that eat those plants may have less food.

• Other animals immediately take the place of bees, so the food chain stays balanced.

Mason is studying different animals and their diets. How does the mouth structure of an animal relate to its diet?

Answer explanation

The mouth structure of an animal, such as teeth shape and jaw type, is adapted to its diet. Herbivores have flat teeth for grinding plants, while carnivores have sharp teeth for tearing meat, reflecting their dietary needs.

What is the importance of scavengers and decomposers in a food chain?

• Scavengers help plants grow directly, while decomposers prevent animals from eating too much.

• Scavengers remove dead matter, and decomposers break it down into nutrients for the soil.

• Scavengers produce food for plants, while decomposers eat living animals.

• Scavengers and decomposers only compete for food in an ecosystem.
