To survive and flourish in any environment , organisms must adapt to the changes in the environment '. Explain the possibilities by which organisms cope up with changing environmental conditions.

Explain the ways by which organisms adapt to survive and flourish in response to abiotic factors .

Organism can maintaimn their internal environment despite change in external environment is called as

Under changing environment sudden development of new tissues and organs occurs in living organisms.

Paragraph based Questions : Read the paragraph and answer the questions given below : Remediation is the process of removing dangerous or poisonous substances from the environment, or limiting the effect that they have on it. When any biological organism is used for remediation, it is called bioremediation. When plant species are used for the purpose of remediation, it is called phytoremediation. When any microbes are used then it is named as microbial remediation. The methods of such remediation have helped to clean the environment from toxic effluents, especially sewage and crude oi]. Dr. Anand Chakraborty, a scientist of Indian origin, has worked on Pseudomonas aeruginosa which have reduced the crude oil films into carbon dioxide and water. Which environmental pollutant is mainly removed through bioremediation processes?

Which group of animal depend on their environment for temperature regulationi.e. they change body temperature according to temperature of environment.

Answer the following Read the paragraph and answer the questions given below it. Food poisoning can occur due to contamination of food by various bacteria and fungi.Clostridia are bacteria responsible for spoilage of cooked food. There are around 100 species of this bacteria viz. Clostridium tetani, Clostridium botulinum, etc. that are present either free living in soil or the alimentary canal of humans and other animals. The bacteria are rod- shaped and produce pottle-shaped endospores in adverse environmental conditions. These microbes cannot withstand normal oxygen levels in air and grow under anaerobic conditions. Do you know about any rod-shaped, anaerobic micro-organism that is useful to humans?
