b) Aerobic respiration uses O2 as the final electron acceptor, whereas anaerobic respiration uses H2O. c) Aerobic respiration uses oxygen as the final electron acceptor, and anaerobic respiration uses either an inorganic molecule, such as nitrate ions or sulfate ions, or an organic molecule, such as an acid or alcohol.

Divisions of labor are ubiquitous in nature and can be found at nearly every level of biological organization, from the individuals of a shared society to the cells of a single multicellular organism. Many different types of microbes have also evolved a division of labor among its colony members.

Verified by Toppr. Two ways in which glucose is oxidized to obtain or produce energy are as follows-. 1) Anaerobic respiration: This process involves the breakdown of glucose into a three-carbon molecule called pyruvate in the absence of oxygen and takes place in the cytoplasm.

Aerobic vs. Anaerobic Respiration: A Comparison. Aerobic respiration, which takes place in the presence of oxygen, evolved after oxygen was added to Earth’s atmosphere. This type of respiration is useful today because the atmosphere is now 21% oxygen. However, some anaerobic organisms that evolved before the atmosphere contained oxygen have.

Why are Living Organisms Classified? Total numbers of organisms already discovered are about 8.7 millions. Among them 6.5 millions are terrestrial and 2.2 millions are aquatic.The largest group of organisms are arthropods, contains about 75% of the total animal community. Discovery of living organisms every year is a continuous process.

The increased level of the nutrients in the water affect the survival of aquatic organism which may leads to the increases population of algae. The level of oxygen is decreases in the water because a lot of oxygen is utilized in this process. When the dissolved oxygen is decreased, then the organisms died who lived in the water.

The producers are the plant species which trap the energy from the sun and nutrients from the soil for the production of food in the form of carbohydrate. The other organisms which cannot prepare the food, depend on the producers are known as the heterotrophs. These are the consumers which feed on the producers. Thus, the correct answer is.

The majority of life on Earth is based on a food chain which revolves around the Sun, as plants use sunlight to make food via photosynthesis. However, in environments where there is no sunlight and thus no plants, organisms instead rely on primary production through a process called chemosynthesis, which runs on chemical energy.

In a food chain, each step representing an organism forms a trophic level. (b) If we kill all the organisms in one trophic level, then the transfer of food (and energy) to the next trophic level will stop due to which the organisms of next trophic level will starve and die or migrate to other areas. The killing of all the organisms in one.

Name the energy currency in the living organism. When and where is it produced? Answer 2 people found it helpful satyaswaroopsethy Answer: The energy currency in the living organisms is ATP. it is produced in mitrocondria. it is formed during cellular respiration.
