Keystone Species: A keystone species is a species that plays a critical role in maintaining the structure and stability of an ecosystem. If a keystone species is removed, the ecosystem can drastically change or even collapse.

Niche: The niche of a species refers to its role or function in the ecosystem, including its place in the food chain, what it eats, where it lives, and how it interacts with other species.

Abiotic Factors: Abiotic factors are non-living components of an ecosystem that can influence the survival and growth of organisms, such as temperature, sunlight, water, soil, and air quality.

Symbiotic Relationship: A symbiotic relationship is a close and long-term interaction between two different species. There are three main types of symbiotic relationships: mutualism, where both species benefit; commensalism, where one species benefits and the other is unaffected; and parasitism, where one species benefits at the expense of the other.

Environmental Issue: An environmental issue is a problem or concern related to the degradation or destruction of the environment, such as pollution, deforestation, climate change, loss of biodiversity, or habitat destruction. Addressing environmental issues is crucial for the health and well-being of ecosystems and all living organisms.
