Biodiversity provide clean air, fresh water, medicines and food security which is also limit to disease and stabilize the climate.
Biodiversity or biological diversity is defined as the variety and variability of life on Earth as a measure of variation at the genetic, species and ecosystem levels. It is described as the great diversity of life on Earth which can be used to refer to all the species in a particular area or ecosystem. Biodiversity is means to every living thing, including plants, bacteria, animals and humans.
The three levels of biodiversity are as follows:
Thus, the Biodiversity provide clean air, fresh water, medicines and food security which is also limit to disease and stabilize the climate.

1. Ecological stability
Each species performs a particular function within an ecosystem. They can capture and store energy, produce organic material, decompose organic material, help to cycle water and nutrients throughout the ecosystem, control erosion or pests, fix atmospheric gases, or help regulate climate.
Ecosystems provide support of production and services without which humans could not survive. These include soil fertility, pollinators of plants, predators, decomposition of wastes, purification of the air and water, stabilisation and moderation of the climate, decrease of flooding, drought and other environmental disasters.
Research show that the more diverse an ecosystem the better it can withstand environmental stress and the more productive it is. The loss of a species thus decreases the ability of the system to maintain itself or to recover in case of damage. There are very complex mechanisms underlying these ecological effects.
2. Economic benefits to humans
For all humans, biodiversity is first a resource for daily life. Such 'crop diversity' is also called agrobiodiversity.
Most people see biodiversity as a reservoir of resources to be drawn upon for the manufacture of food, pharmaceutical, and cosmetic products. Thus resource shortages may be related to the erosion of the biodiversity.
Some of the important economic commodities that biodiversity supplies to humankind are:
- FOOD : crops, livestock, forestry, and fish
- MEDICATION: Wild plant species have been used for medicinal purposes since before the beginning of recorded history. For example, quinine (Used to treat malaria) comes from the bark of the Amazonian tree Cinchona tree; digitalis from the Foxglove plant (chronic heart trouble), and morphine from the Poppy plant (pain relief).
According the National Cancer Institute of the USA, over 70 % of the promising anti-cancer drugs come from plants in the tropical rainforests. Animal may also play a role, in particular in research. It is estimated that of the 250,000 known plant species, only 5,000 have been researched for possible medical applications.
- INDUSTRY: fibres for clothing, wood for shelter and warmth. Biodiversity may be a source of energy (such as biomass). Other industrial products are oils, lubricants, perfumes, fragrances, dyes, paper, waxes, rubber, latexes, resins, poisons and cork can all be derived from various plant species. Supplies from animal origin are wool, silk, fur, leather, lubricants, waxes. Animals may also be used as a mode of transportation.
- TOURISM & RECREATION: biodiversity is a source of economical wealth for many areas, such as many parks and forests, where wild nature and animals are a source of beauty and joy for many people. Ecotourism in particular, is a growing outdoor recreational activity.
3. Ethical reasons
The role of biodiversity is to be a mirror of our relationships with the other living species, an ethical view with rights, duties, and education. If humans consider species have a right to exist, they cannot cause voluntarily their extinction. Besides, biodiversity is also part of many cultures’ spiritual heritage.
b.light energy to chemical energy
c.chemical energy to light energy
d.the energy of motion to sound energy
Correct Option Is b. light energy to chemical energy.
The energy conversion of light energy to chemical energy, known as photosynthesis, occurs in plant cells but not in animal cells.
The energy conversion that takes place in plant cells but never in animal cells is the conversion of light energy to chemical energy. This critical process is called photosynthesis.
During photosynthesis, plants absorb light energy, usually from the sun, and transform it into chemical energy stored in the form of glucose or other sugars. This chemical energy is then used by the plant for growth and development.
On the other hand, animal cells do not have the capability to carry out photosynthesis because they lack the necessary organelle, chloroplasts, and pigments required for absorbing light energy.

Eukaryotic cells are cells that have a nucleus and membrane-bound organelles.
Eukaryotic cells have a membrane around the nucleus that separates them from the cytoplasm. Inside the nucleus are the nucleic acids and inside the cytoplasm are all the organelles necessary for the functioning of the cells.
Eukaryotic cells are more complex than prokaryotic cells because of their configuration.
Prokaryotic cells, on the other hand, do not have a nucleus, so the nucleic acids are loose in the cytoplasm and are not separated from the other organelles, which in this type of cell are few and less complex than those of eukaryotic cells.
