Answer:
=) salmon
Explanation:
The primary cause of these orcas deaths is starvation. The southern residents—which include the J, K, and L-pods—survive mainly on Chinook salmon, another species in decline due to overfishing, hydroelectric projects, and the harbor seals that get to them before they make their way to Puget Sound
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.
Answer:
In which class of elements is there a greater range of properties, the metals or the nonmetals? Give an example to support your answer. Non-metals have greater range of properties given that they exist as solids, liquids and gases. And also that they can polymerize, crystallize and form organic compounds.
