Time: 90 mins | Marks: 45 | Difficulty: Medium
multiple choice question

Q1. Which of the following is a biotic component of an ecosystem? 

  1. Sunlight
  2. Grass
  3. Soil 
  4. Temperature

Q2. Which group forms the primary producers in most ecosystems?

  1. Green plants
  2. Herbivores
  3. Carnivores
  4. Decomposers

Q3.Which of the following is an abiotic component of an ecosystem?

  1. Bacteria
  2. Earthworm
  3. Water 
  4. Grasshopper

Q4. A school garden contains plants, insects, birds, soil, water, air and sunlight. Which statement best describes this garden?

  1. It contains only biotic components
  2. It contains only abiotic components
  3. It contains both biotic and abiotic components
  4. It is not an ecosystem because it is artificial

Q5.Which of the following is most likely to be considered a natural ecosystem?

  1. Aquarium
  2. Crop field
  3. Forest
  4. Artificial pond

Q6. An aquarium maintained by humans is generally classified as:

  1. A natural ecosystem
  2. An artificial ecosystem
  3. An abiotic ecosystem
  4. A decomposer ecosystem

Short questions

Q1. What is an ecosystem? Name its two major types of components.

Q2. Differentiate between biotic and abiotic components of an ecosystem with one example of each.

Q3. What role do producers play in an ecosystem?

Q4. Why are decomposers important for maintaining an ecosystem?

Q5. Your school has a small garden containing flowering plants, butterflies, ants, birds, soil and water.

Identify any two biotic and two abiotic components present in this garden.

Q6. A student visits a forest in Uttarakhand and later observes a fish aquarium at home.

How would you classify these two ecosystems? Give one reason for each classification.

long questions

Q1. Explain the major components of an ecosystem. Discuss the roles of producers, consumers, decomposers, and abiotic factors in maintaining the ecosystem.

Q2. Differentiate between natural and artificial ecosystems. Give suitable examples and describe how human activities may influence an artificial ecosystem.

Q3. Consider a pond containing algae, aquatic plants, fish, frogs, insects, bacteria, water, dissolved minerals, sunlight and temperature variations.

Classify these components into appropriate groups and explain how both living and non-living components work together to make the pond a functioning ecosystem.

application-based questions

Q1. A student records 32 different components in a school garden. Among them, 19 are living components and the remaining are non-living components.

a) How many non-living components were recorded?
b) What percentage of the recorded components were living?

Q2. During a field visit, students identify the following numbers of components in a pond ecosystem:

  • Producers: 8

  • Herbivores: 6

  • Carnivores: 4

  • Decomposers: 2

a) Find the total number of identified living components.
b) What percentage of the identified living components are producers?

Q3. Two ecosystems are surveyed for their major components.

a) Calculate the total number of identified components in each ecosystem.
b) Which ecosystem has the greater total number of identified components, and by how many?
