Ecosystems

Ecosystems are a key concept in biology, and they play a crucial role in sustaining life on Earth. In the NEET syllabus, ecosystem is a topic that is given a weightage of about 2 percent, which highlights its importance in the study of biology.
An ecosystem is a community of living organisms, such as plants, animals, and microorganisms, interacting with one another and their non-living environment, such as air, water, and soil. The interactions within an ecosystem are complex and interdependent, and any disturbance to one component can have ripple effects throughout the entire ecosystem.
Thus, studying ecosystems is important not only for understanding the natural world but also for developing strategies to conserve and manage the biodiversity and resources that ecosystems provide.
