If one million kilocalories of energy are stored in producers in an ecosystem, how many kilocalories can be transferred to terti
Mashcka [7]
The answer is 1000 kilocarolies.  It is important to keep in mind that Energy is passed up the food chain from one trophic level to the next but a lot of it is lost along the way. Energy is passed up the food chain from one trophic level to the next. However, only about 10% of the total energy stored in organisms at one trophic level is actually transferred to organisms at the next trophic level. Therefore; if the producers have 1 million kilocarolies, then  the energy transferred to the primary consumer will be 100,000 kilocalories (10% of a million), and the energy transferred to the secondary consumer will be 10,000 kilocalories (10% of 100,000) and the energy to the tertiary consumer will be 1000 kilocarolies (10% of 10,000).

On an island, finches that fed on large, hard seeds had large beaks. Finches with small beaks fed on small, soft seeds. A drough
Stolb23 [73]

Answer:

The correct options are:

  • <em>The population of birds with large beaks will increase on the island.</em>
  • <em>The trait for large beaks will be passed on to future generations through natural selection.</em>

Explanation:

According to the theory of natural selection, those organisms tend to survive in an environment which are better adapted to live in an environment and which can better adapt to changes that occur in an environment.

The drought caused the small, soft seeds to decrease more in number as compared to the large, hard seeds. As a result, the birds having large beaks were better adapted to live in the environment as compared to the birds having small beaks. So the population of the large beak birds increased and they passed their characteristics to the future generations.
