Natural Resources and Their Use Class 8 Passage Based Questions
1. Read the following passage carefully and answer the questions that follow:
Ecosystem functions and ecosystem services: Nature has some inherent ways of working. For example, trees naturally produce oxygen. When these natural processes benefit humans, we call them 'ecosystem services'. We can think of it like this: a forest naturally filters water, prevents soil erosion, and provides habitat for animals - these are ecosystem functions. When we benefit from clean water, protected farmland, and pollinated crops because of that forest, we are receiving ecosystem services from Nature.
Question 1.
Which of the following is an ecosystem function?
(a) Oxygen supply for breathing
(b) Farming
(c) Photosynthesis by plants
(d) Foods for humans and animals
Answer:
(c) Photosynthesis by plants
Question 2.
When humans use clean water filtered naturally by forests, it is called:
(a) Ecosystem function
(b) Ecosystem balance
(c) Ecological pyramid
(d) Ecosystem service
Answer:
(d) Ecosystem service
Question 3.
Pollination by bees becomes an ecosystem service when it leads to :
(a) Production of fruits and crops for human use
(b) Transfer of pollen
(c) Growth of flowers
(d) Habitat creation
Answer:
(a) Production of fruits and crops for human use
Question 4.
What kind of benefit/benefits do we get from trees releasing oxygen?
(a) Forest growth
(b) Animal habitat
(c) Human and animal respiration
(d) Soil fertility
Answer:
(c) Human and animal respiration
