Chapter 6: Problem 19

Which one of the following is a herbivore? (a) Man (b) Deer (c) Lion (d) Bear

Short Answer

Expert verified
a) Man b) Deer c) Lion d) Bear Answer: b) Deer

Step by step solution

01

List the options and their diets

First, let's list down the options given in the exercise and the type of food each animal consumes: (a) Man - Omnivore (eats both plants and animals) (b) Deer - Herbivore (eats plants) (c) Lion - Carnivore (eats primarily meat) (d) Bear - Omnivore (eats both plants and animals)
02

Identify the herbivore

Now that we know the diets of each of the options, we can easily identify the herbivore from the list. In this case, option (b) Deer is a herbivore, as it primarily consumes plants.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Animal Diets
Animals have diverse diets which greatly influence their roles in the ecosystem. The diets of animals can be primarily divided into three main categories:
  • Herbivores: These animals feed mainly on plants, leaves, fruits, flowers, and bark. Their digestive systems are specially adapted to process plant materials efficiently.
  • Carnivores: These animals primarily consume other animals. Carnivores have adapted to hunt and eat meat, using sharp teeth and claws.
  • Omnivores: Animals that eat both plants and animals are known as omnivores. They have versatile dietary habits that allow them to consume a wide range of food items.
Understanding animal diets is crucial in ecology, as it helps us to identify the niche they occupy in their habitats.
Types of Consumers
In ecological terms, consumers are organisms that receive energy by feeding on other organisms. Consumers are broadly categorized based on their food sources:
  • Primary Consumers: These are herbivores that consume primary producers, like plants and algae, directly. They form the base of the consumer food chain.
  • Secondary Consumers: These include carnivores or omnivores that feed on primary consumers. They play a pivotal role in controlling herbivore populations.
  • Tertiary Consumers: These are predators at the top of the food chain that prey on secondary consumers. They help maintain ecological balance by keeping the animal population in check.
Each type of consumer has a specific role that maintains the health and stability of their ecosystems.
Herbivore Examples
Herbivores are incredibly diverse and found in various habitats across the globe. Let's explore some common examples:
  • Deer: Known for grazing on grass, leaves, and twigs, deer are classic examples of herbivores in forests and grasslands.
  • Cows: Domesticated for agriculture, cows primarily consume grass and hay.
  • Elephants: These large mammals primarily eat leaves, bark, and fruit, using their trunks to feed.
  • Rabbits: Known for feeding on wild vegetation and garden plants, rabbits are small, fast herbivores that rely on plants for sustenance.
  • Pandas: Unlike many bears, pandas are herbivores that primarily eat bamboo.
These examples highlight the diverse nature of herbivores, each uniquely adapted to extract nutrients from plant-based food sources.
