Answer: A. 1
Mangrove swamps are wetland ecosystem found in the coastal area. These are found in regions where water body and terrestrial land meets. These ecosystem are dominated by mangrove trees due to their ability to servive in harsh saline water conditions. The roots of mangrove trees exhibit salt filteration system. These trees are habitat of many bird and animal species. The roots of these trees provide shelter, to underwater aquatic plant and animal species such as algea, prawns, sponges and fishes. Mangroves trees and algea are primary producers of the food chain in mangrove ecosytem. Mangrove tree leaves are eaten up by herbivores insects and algal species are consumed by large number of sea animals. Hence, mangrove tree and algea will be on the 1 number of the food chain.
Two unicorns with no horns could have an offspring if the horn trait is recessive and the no-horn trait is dominant. There would be a 25% chance of the offspring from these two unicorns having a baby unicorn with a horn.
Answer:
The correct answer is - option 1. 930 kilocalories.
Explanation:
In every ecosystem, the energy is passed from one form to another and there is a lot of loss of the energy as heat in the cellular process. There is a transfer of only 10% of each level of the trophic level.
Algae is the producers in this aquatic ecosystem so the primary consumer will get 10% of the energy that is present in plant tissue (93000kcal) which will be 9300 Kcal and second producers will get 10% of this will be 930Kcal.
Thus, the correct answer is option 1. 930 kilocalories.
