Answer:
An index fossil is a fossil used to determine the age of the sediments in which it is found. When quickly approximating the age of new finds, an archaeologist looks at the rocks in which it is buried, as those sediments would have been on the surface at the time of the death of the pre-historic creature.

Explanation:
Photosynthesis is a process taking place in the green plants which are involved in the formation of the glucose molecule using Carbon dioxide and water in the presence of sunlight.
The process of photosynthesis takes place in two phases:
1. Light-dependent phase
2. Light independent phase
<u>Light-dependent phase
</u>
Light-dependent phase takes place in the thylakoid membrane where the Photosystem I and II are present.
The photosystem II absorbs the sunlight of 680 nm wavelength which excites the electron of the chlorophyll. The electron moves in the photosystem and through the reaction center-exit the photosystem and enters the electron transport chain.
The electron is then transferred via the electron carriers like plastoquinone, cytochrome, and plastocyanin and is transferred to photosystem I which absorbs the light at 700 nm. From here the electron is taken by ferrodoxin and form NADH.
The electron then reaches the ATP synthase and forms the ATP molecules thus ATP and NADPH are formed in the reaction but the loss of electron in chlorophyll is fulfilled by the water molecule which on hydrolysis provides the electrons and stabilize the structure.
<u> Light independent phase
</u>
The phase during which the Rubisco enzyme binds with the carbon dioxide and forms 3-PGA. This 3 PGA is then reduced to G3P which requires the 6 ATP molecules. The G3P molecule then forms 1 molecule of glucose and the Rubp is again regenerated.
It is safe to assume that the eastern kingbird will have a <u>type 2 </u><u>functional response </u><u>to an increase in </u><u>prey abundance</u><u>.</u>
The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:
- Type 1: An increase in consumption
- Type 2: A decrease in consumption
- Type 3: Decreased consumption, followed by a quick increase.
The Eastern kingbird is likely to follow a <u>type 1 </u><u>functional response</u> to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.
