Key Points of Class 10 Science Chapter 13
-
An ecosystem is made up of a complex of biological and abiotic elements that interact with one another. Biological elements include the producers, users, recyclers. Abiotic elements include physical elements such as the environment, temperature, humidity, water, soil, etc.
-
A food chain is the process of transporting energy from one level of the food chain to another by consuming organisms. A food web is a collection of food chains that represent feeding relationships in an ecosystem.
-
Energy circulates in a one-way direction through the ecosystem, while nutrients circulate within the ecosystem. Nutrient cycles include carbon cycles, nitrogen cycles, and water cycles.
-
Biodiversity is the diversity of life on Earth. It includes the diversity of species, the diversity of genetic makeup, and the diversity of ecosystems. Biodiversity is important for the maintenance of ecological equilibrium, ecosystem services and sustainable development.
-
Deforestation refers to the destruction of forests for a variety of purposes.
-
Habitat destruction, soil degradation, water loss, and climate change are some of the main impacts of deforestation.
-
Desertification is a type of land degradation that happens in areas that are either arid or semi-arid. To stop desertification, it's important to protect the soil, plant new trees, and use land in a sustainable way.

Question 2: What is biodiversity?
Answer 2: Biodiversity is the broad range of life forms found on the planet, including genetic variability, species variability, and ecosystem variability. It includes the various plant, animal, and microbial species, as well as the ecosystems in which they exist.
