Explore What’s Inside a Forest: Sort and Classify the Living Things in a Forest.
Let your students explore what really lives within a forest using this sorting and classifying activity. Ask them to think about the different organisms that call the forest home and have them sort them into categories such as animals, plants, fungi and so on. Encourage them to think about how the organisms depend on each other for survival and why forests are so important for our planet’s ecosystems.

What Would Happen if There Were No Forests? Write About It. 

Ask your students to imagine what would happen if we no longer had any forests and then have them write down their thoughts. Talk to them about the consequences of deforestation, such as a lack of food sources, disruption of wildlife habitats, loss of species and an increase in global warming. Point out how it would also take away recreational sites for humans and deplete our natural resources. Show them why forests need to be saved and how important it is that we protect these vital areas for future generations.

Forests are an essential part of our ecosystem, and it is crucial to protect them for the survival of life on Earth. Forests help regulate the climate, prevent soil erosion, purify the air and water, and provide habitats for numerous species of plants and animals.

forests our lifeline class 7 extra questions and answers

  1. What is a forest?

Answer: A forest is a large area of land covered with trees and undergrowth.

  1. Why are forests important for us?

Answer: Forests are important for us because they provide us with many essential things like oxygen, wood, medicines, fruits, and nuts. They also help to maintain the balance of nature and prevent soil erosion.

  1. What are the main functions of a forest?

Answer: The main functions of a forest are:

  • Providing oxygen
  • Providing wood and other forest products
  • Regulating the water cycle
  • Maintaining the balance of nature
  • Supporting biodiversity
  • Preventing soil erosion
  • Reducing the impact of natural disasters
  1. What is deforestation?

Answer: Deforestation is the removal of forests or trees from a large area of land, usually due to human activities such as agriculture, urbanization, or mining.

  1. How does deforestation affect the environment?

Answer: Deforestation affects the environment in many ways. It causes soil erosion, reduces the amount of oxygen in the air, destroys habitats, and increases the risk of flooding and landslides. Deforestation also contributes to global warming, as trees absorb carbon dioxide from the air.

  1. What is afforestation?

Answer: Afforestation is the process of planting trees in an area where there was no forest. It is done to increase the forest cover and combat the effects of deforestation.

  1. What are the advantages of afforestation?

Answer: The advantages of afforestation are:

  • Increases the forest cover
  • Provides habitats for wildlife
  • Helps to prevent soil erosion
  • Absorbs carbon dioxide from the air, thus reducing the impact of global warming
  • Provides wood and other forest products
  • Helps to regulate the water cycle
  1. What are the different types of forests?

Answer: The different types of forests are:

  • Tropical rainforests
  • Temperate forests
  • Boreal forests
  • Deciduous forests
  • Evergreen forests
  1. What is the difference between a tropical rainforest and a temperate forest?

Answer: Tropical rainforests are found near the equator and have high rainfall and humidity, while temperate forests are found in areas with moderate climate and rainfall. Tropical rainforests are characterized by dense vegetation and a wide variety of plant and animal species, while temperate forests have more seasonal changes and fewer species.

  1. How can we conserve our forests?

Answer: We can conserve our forests by:

  • Planting more trees
  • Avoiding deforestation
  • Supporting sustainable forestry practices
  • Reducing our carbon footprint
  • Encouraging eco-tourism
  • Promoting conservation efforts and awareness

Points to remember ( notes)

Forest is an area with large numbers of trees that serves as a natural habitat for animals and plants. Some of the famous forests in the world are spiny forests, Madagascar, Sikkim pine forest (India), The amazon rainforest, South America, and more.

Afforestation is the planting of trees over a large region where deforestation has taken place.

An ecosystem is a biological environment that includes all the living and non-living components of a particular area.

branchy part of a tree above the stem is known as the crown. trees had crowns of different types and sizes. These had created different horizontal layers in the forest. These are known as understoreys Giant and tall trees constituted the top layer followed by shrubs and tall grasses, and herbs formed the lowest layer.

The branches of the tall trees look like a roof over the other plants in the forest is called a canopy

All animals, whether herbivores or carnivores depend ultimately on plants for food. Organisms that feed on plants often get eaten by other organisms, and so on. For example, the grass is eaten by insects, which in turn, is taken by the frog. The frog is consumed by snakes. This is said to form a food chain: Grass- insects- frog- snake- eagle. Many food chains can be found in the forest. All food chains are linked. If one food chain is disturbed, it affects any other food chain. Every part of the forest is dependent on the other parts. If we remove one component, say trees, all other components would be affected.

The micro-organisms which convert the dead plants and animals to humus are known as decomposers. These micro-organisms play an important role in the forest.

Forests provide us with oxygen. They protect soil and provide habitat to a large number of animals. Forests help in bringing good rainfall in neighboring areas. They are a source of medicinal plants, timber, and many other useful products. If forests disappear, the amount of carbon dioxide in the air will increase, resulting in an increase in the earth’s temperature.


Q: What is the importance of forests? A: Forests are important for maintaining ecological balance and sustaining life on earth. They provide clean air, regulate the water cycle, support biodiversity, prevent soil erosion, and act as carbon sinks to reduce the impacts of climate change.

Q: How do forests help in preventing soil erosion? A: Forests prevent soil erosion by acting as a barrier against the wind and water that can erode the topsoil. The roots of trees hold the soil in place, and their fallen leaves and other organic matter help to retain moisture in the soil, making it less prone to erosion.

Q: How do forests help in maintaining the water cycle? A: Forests help to maintain the water cycle by absorbing water from the soil and releasing it into the atmosphere through the process of transpiration. This moisture then forms clouds and falls as rain or snow, replenishing the water sources on earth.

Q: What is the role of forests in supporting biodiversity? A: Forests are home to a wide variety of plant and animal species, many of which are unique to specific forest ecosystems. They provide habitats and food sources for these species, and their preservation is critical to maintaining biodiversity.

Q: What are the threats to forests? A: The major threats to forests are deforestation, illegal logging, forest fires, climate change, and habitat fragmentation. These threats can lead to the loss of biodiversity, soil degradation, and decreased water availability, among other impacts.

Q: What are some ways to conserve forests? A: Forests can be conserved through sustainable forestry practices, protected areas, reforestation efforts, and reducing the demand for products that contribute to deforestation, such as palm oil and beef. It is also important to involve local communities and indigenous peoples in forest conservation efforts
