How does ozone layer affect an ecosystem?

Answer 1

As a "shield", it prevents certain wavelengths of UV from passing. As an occasional event (lightning), it destroys odorous compounds. With chronic (long term) exposure. it damages / destroys plants ability to respire, and animal's lung tissue. Ozone is used by marigolds to fight root parisitism, and by white blood cells to fight infection. In aquaria, ozone plays an important part in purification of water (reactivation of natural bromine), with similar damage to fish's gill structures under high ozone concentrations or long term exposure.

Answer 2

Ozone is a colourless gas that acts as a screen for ultraviolet radiation. It is continuously formed at the higher levels of the atmosphere due to the action of UV rays on molecular oxygen. The high energy UV radiations break down O2 molecules into nascent oxygen.

Then, this free oxygen atom combines with an oxygen molecule to form ozone.

In recent years, the amount of ozone in the atmosphere is getting depleted.

This ozone depletion causes a greater amount of ultra violet radiation to enter earth's atmosphere. This has an indirect effect on the ecosystem.(Ecosystemincludes both the biological community and the non-living components of an area). It results in the death of many phytoplanktons, thereby affecting the process of photosynthesis. Plants utilise atmospheric CO2 to make their food. In the absence of plants, the levels of CO2 in the atmosphere will increase, which would in turn lead to an increase in global warming.

The depletion in the ozone layer also increases the frequency of Infectious Diseases as it suppresses the immune systems of both human beings and animals. The frequency of skin cancer also increases in human beings because of the direct exposure to ultraviolet radiations.

Answer 3

The ozone layer protects ecosystems by absorbing the majority of the sun's harmful ultraviolet radiation, which can cause DNA damage, lower crop yields, and harm aquatic life. Depletion of the ozone layer can lead to increased levels of UV radiation reaching the Earth's surface, which can disrupt ecosystems by affecting plant growth, disrupting food chains, and causing harm to animals.

Answer 4

Ozone absorbs short wave UV that can damage plants and animals exposed to it. Crop yields are reduced. Mutation is produced.

Answer 5

Ozone hole causes UV rays to enter the earth. they can cause fatal problems to living beings thus destroying the ecosystem.
