speech on biodiversity
Answers
ANSWER BY CUTESMILE :
The word ‘biodiversity’ is a combination of two words: biological and diversity. It refers to the variety of life on Earth and encompasses all the living things that exist in a certain area, in the air, on land or in water: plants, animals, microorganisms, fungi.
The area considered may be as small as your backyard compost heap or as big as our whole planet. Animals and plants don’t exist in isolation. All living things are connected to other living things and to their non-living environment (earth forms, rocks and rivers). If one tiny species in an ecosystem becomes extinct, we may not notice, or think it’s important. But the biodiversity of that ecosystem will be altered, and all the ecosystems that the species belonged to will be affected.
Biological diversity therefore refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency.
For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance.
Biological diversity is defined as the variability among living organisms from all sources including terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.
