The general requirement for energy and materials is common to all living organisms. Living beings need plants and trees in order to survive, as most of their needs are met by them.
Read the passage and answer the questions.
(i) Do plants also depend on some source for food production? Explain.
(ii) How do we derive nutrition for survival? How does this nutrition vary among different organisms?
(iii) What do we learn concerning the increased cutting of trees and removal of the green cover?
Answers
Answer:
1.All living organisms require food. Plants can make their food themselves but animals including humans cannot. They get it from plants or animals that eat plants. Thus, humans and animals are directly or indirectly dependent on plants
2.Such organisms depend on others for their nutrition. The organisms which cannot produce food on their own and depend on other sources/organisms are called heterotrophs. This mode of nutrition is known as heterotrophic nutrition. ... Thus we can say survival of heterotrophs depends directly or indirectly on plants.
3.The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
Cutting down of trees are essential for wood, to produce paper and other applications.
Explanation:
- However, extensive logging and few other activities that kill trees lead to deforestation. This process affects the ecosystem by turning forests into barren lands with little or no vegetation.
- Plants are necessary to create oxygen for human survival, and also absorb green house gases. Without trees, there will be an increase in the level of greenhouse gases in the atmosphere, causing global warming and drastic change in global temperature.
