Answer:
Two adaptations of Darwin's Finches that helped them to survive are:
- Behavioral adaptations to use tools for foraging.
Explanation:
There are fourteen species of Darwin's finches that originated from a single species of ground dwelling seed eating finch.
These Finches occupied different niche in the Galapagos island and were widely studied by Darwin.
These finches are one of the best Examples of Adaptive radiation.
Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.
These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.
Only birds who had large and hard beaks could feed on these hard dry seeds.
To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.
Some groups started feeding on insects and got their beaks adapted to capture and kill insects.
Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.
Quantity of blood delivered to various parts of the body.
Answer:
The organism to have maximum energy would be the algae since ii will be at the lowest level. so the answer is 'B'.
Explanation:
The pyramid of energy shows the flow of energy from one trophic level to other. The lowest trophic level is occupied by the producers. In this case algae acts as the producer. Krill acts as the primary consumer, followed by leopard seal as the secondary consumer and finally killer whale as the tertiary consumer. The <em>lowest trophic level </em> contains maximum energy.
As we go upwards, only 10% of the energy gets transferred to the next trophic level.
