Answer:
The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.
Explanation:
An ecosystem is a basically a community in which several living organisms live together in a certain area and share food and other living resources.
When we talk about prime source of energy for any ecosystem it is considered to be the, Sun. Sun is the source of energy for all living organisms and the energy of sunlight is primarily used by green plants to prepare food through the process of photosynthesis. In this process sunlight is fixed into energy compounds like ATP. And once the green plants are eaten by other higher animals like goat, some of the energy is wasted as heat and other is transferred into the body of next organism. Then when the goat is eaten by higher animal like lion, some of the energy is wasted as heat and other is transferred into the body of next organism. This process goes on.
In this way, the energy from sun is transferred from herbivores like goat to carnivores like lion etc. Some energy is used by the higher organisms while the other is lost as heat during energy transfer process.
Therefore, mentioned option,<em> "The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat" </em>is correct option.
Option A is the correct answer
Reason:
Due to the low temperature and very high rainfall, the Crop could not grow properly in European nation. Due to this , the people devoid of food reached at the verge of dying. After certain point of time there was feminine. The effect were so devastating that these lasted even after the winter season was over. Lack of food raised the price of food item
Black whole because if it’s asking u which of the first stage in the life cycle
Answer:
The correct answer will be option-C
Explanation:
Replication is a complex process which makes copies or replicates the DNA in every organism present on the Earth. Replication is an ATP dependent process which is catalysed by several enzymes including DNA helicase, polymerase, primase.
During replication, the two strands are synthesized from parent strand in which the strand which is synthesized in 5' to 3' direction is known as the leading strand which is continuous whereas another strand synthesized in 3' to 5' direction is known as lagging strand as it is produced in the lags.
Since in the leading strand DNA polymerase adds nucleotides at 3' end, therefore, it requires only one RNA primer which assists DNA polymerase to proceed the reaction whereas in the lagging strand since the strands are synthesized in the lags so possess many RNA primers so that DNA polymerase can bind.
Thus, option-C is the correct answer.
