Ans. Ecology is the scientific study of interactions between living organisms and their environment. It explores how organisms interact with each other and their physical and biological surroundings, including the impacts of human activities on these interactions.
| 2. What are the levels of ecological organization? | |
Ans. The levels of ecological organization are individual organisms, populations, communities, ecosystems, and biosphere. Individual organisms are the basic unit of ecology, while populations refer to groups of individuals of the same species. Communities are groups of populations living in the same area, while ecosystems involve the interactions between living organisms and their physical environment. The biosphere encompasses all ecosystems on Earth.
| 3. Why is ecology important? | |
Ans. Ecology is important because it helps us understand the complex interactions between organisms and their environment. It provides insights into how ecosystems function, how biodiversity is maintained, and how human activities can impact the natural world. By studying ecology, we can develop strategies to conserve and manage natural resources, protect endangered species, and mitigate the effects of climate change.
| 4. What are some examples of ecological issues? | |
Ans. Some examples of ecological issues include habitat destruction, pollution, climate change, overfishing, and invasive species. These issues can have significant impacts on ecosystems, leading to a loss of biodiversity, altered nutrient cycles, and reduced ecosystem services.
| 5. How can individuals help promote ecological sustainability? | |
Ans. Individuals can promote ecological sustainability by reducing their carbon footprint, conserving water and energy, supporting sustainable agriculture and forestry practices, reducing waste, and supporting conservation efforts. Small actions, such as using reusable bags and water bottles, biking or walking instead of driving, and planting native species, can also make a difference in promoting ecological sustainability.
