The amount of total energy at each trophic level decreases as it moves through, so 90% is lost at each level. This means that only 10 percent of the energy at any trophic level is transferred to the next level; and the rest is lost as heat.
In this case, if a plant ecosystem has 3000000 kilocalories (kcal) of energy, about 300000 kcal will be transferred to primary consumers (for example grass hoppers). If the red-tailed hawks are tertiary consumers, they will get 3000 kcal of energy.
This is an ecosystem energy pyramid that illustrates how much energy is found at each trophic level of a food chain. Select all the statements about this pyramid that are TRUE.
Approximately 90% of energy from one trophic level is transferred to the next trophic level.
Looking at the total amount of energy in an ecosystem, most energy can be found in the primary consumers.
This energy pyramid explains why there are few tertiary consumers in most ecosystems.
Looking at the total amount of energy in an ecosystem, most energy can be found in the producers.
Answer:
You can use either your answer or the sample answer you gave. You are so nice by the way!
Explanation:
THE FOLLOWING ARE TWO ANSWERS YOU CAN CHOOSE FROM
ANSWER 1:
The red crystals are compounds. This is because when the sample is heated, a GAS (element) is released and BLUE POWDER (element) is left. Two elements make up these red crystals. A compound can also be shown through color change - the RED crystals, when heated, turn into BLUE powder. Elements cannot be broken down into substances using physical force, like heating. So yes, this is a compound.
ANSWER 2:
The red crystals are compounds. This is because when the sample is heated, a GAS (element) is released and BLUE POWDER (element) is left. Two elements make up these red crystals. A compound can also be shown through color change - the RED crystals, when heated, turn into BLUE powder. Elements cannot be broken down into substances using physical force, like heating. So yes, this is a compound.
EITHER ONE YOU CHOOSE WILL BE CORRECT, JUST SAYING!
A strictly fermentative bacterium produces energy by glycolysis only.
