Reptiles have a special egg that feeds their young called an amniotic egg. Therefore, option (B) is correct.
Reptiles, birds, and certain mammals reproduce on land thanks to the amniotic egg's extraordinary evolution. Its shell protects the embryo from external dangers and desiccation. The amnion, which encloses the embryo in a fluid-filled chamber, is a key element of the amniotic egg. Amniotic fluid protects the embryo from mechanical shocks and allows gas exchange.
Reptiles can lay eggs on land without returning to water thanks to the amniotic egg, which marks the transition from aquatic to terrestrial life. This adaptability has helped reptiles colonise different ecosystems worldwide. Therefore, option (B) is correct.

6. Energy transfer between organisms normally involves conservation of heat energy.
C. Energy is lost between trophic levels.
Answers
Energy is lost between trophic levels.
Answer: Option C
Explanation:
The source of energy for all organisms is the Sun. The Tropic levels exhibit the flow of energy in an ecosystem. The flow of energy is always in one direction. The energy level decreases crossing each trophic level as energy is lost in the form of heat.
Primary producers are the first in Trophic level, The Herbivores fall in the next level , the Carnivores form the next level and the decomposers are the last in the trophic level. The decomposers decompose all the living organisms and convert to nutrients that are available in the soil. The plants take up this nutrient and hence this is a cycle.
