Why Preserve Biodiversity? ANSWERS
1. Define the term “biodiversity” Biodiversity, or biological diversity, is the term for the variety of life and the natural processes of which living things are a part. This includes the living organisms and the genetic differences between them and the communities in which they occur. The concept of biodiversity represents the ways that life is organized and interacts on our planet. 2. What is ecology? Ecology is the study of organisms and their relationship with their surroundings. Ecologists study the interaction between an organism and its environment. Some ecologists study the interaction of a specific species or habitat; others study the different species that depend on each other (ex. a food web). 3. What is a biome? A biome can be described as an area on our earth that shares the same species, climate, animals, and plants. There are actually about 150 different classified biomes today. The main biomes are Marine, Tundra, Desert, Savannah, Grassland, Tropical Rain Forest, Deciduous Forest, and Coniferous Forest. 4. What is an ecosystem? An ecosystem includes all the abiotic factors in addition to the community of species that exists in a certain area. Human populations depend on plants and animals for much of their food, medicines, clothing, and shelter. Perhaps even more important, intact ecosystems perform many vital functions, like purifying the air, filtering harmful substances out of water, turning decayed matter into nutrients, preventing erosion and flooding, and moderating climate.

5. What is meant by extinction? Name a species on the Niagara Escarpment that is threatened and could become extinct in the future. All living things are part of a complex, delicately balanced network called the biosphere. The earth's biosphere is composed of ecosystems, which include plants and animals and their physical environment. The removal of a single species within an ecosystem can set off a chain reaction affecting many...
