Number of vultures are decreasing remarkably nowadays, which is a matter of concern.
Answer the following questions related to the above given statement: 5
(i) Vultures belong to which category of animals?
(ii) What is their role in nature to maintain ecological balance?
(iii) At which trophic level will you place vultures, in a food chain?
(iv) How much energy is passed on at each trophic level in a food chain? Give the
energy flow diagram of an ecosystem.
(v) Mention one of the main cause for this decline in the number of vultures.

Answer:
i) scavengers
ii) Vultures are often overlooked and perceived as lowly scavengers, but they play a crucial role in the environments in which they live. ... Vultures, also known as nature's cleanup crew, do the dirty work of cleaning up after death, helping to keep ecosystems healthy as they act as natural carcass recyclers
iii) Vultures are scavengers and also carnivores
Thus they occupy the place of tertiary consumer in the tropic level.
iv) he amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat. If a grassland ecosystem has 10,000 kilocalories (kcal) of energy concentrated in vegetation, only about 1,000 kcal will be transferred to primary consumers, and very little (only 10 kcal) will make it to the tertiary level. Energy pyramids such as this help to explain the trophic structure of an ecosystem: the number of consumer trophic levels that can be supported is dependent on the size and energy richness of the producer level.
v) The anti-inflammatory drug diclofenac has been incriminated as the main cause for decline in vulture numbers in South Asia. The birds, it is said, perish after feeding on carcasses that have residues of the drug.
Answer:
A. it belongs to top consumer of carnivores they eat dead bodies of animals and clean the enviroment hence they are also called scavangers of the enviroment.
B. They consume dead animal bodies and clean the enviroment. They also recycled the nutrient into the soil.
