Change of one form of energy into other can occur according to the law of conservation of energy.
Explanation:
According to the law of conservation of energy, energy can not be created or destroyed. However, one energy form can be transformed into another form. These energy transformations also occur in ecosystems.
In the given example, the solar energy from the Sun was used by seagrass to perform the process of photosynthesis.
During the process, the energy from sunlight was converted into the chemical energy of organic nutrients (glucose). Part of these nutrients is used by seagrass as an energy source while rest is stored in its tissues. The transformation of radiant energy from the Sun into the chemical energy of nutrients present in seagrass follows the law of conversation of energy.
Answer:
the sample contains starch and starch is stored in ground tissue.
Explanation:
It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.
This process can simply be demonstrated by simply following these steps.
* Take two potted plants of the same kind.
* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.
* Take one leaf from each of the plants.
* Put few drops of iodine solution on each of the leaves.
* The leaf kept in the sunlight will turn blue-black due to presence of starch.
* The leaf kept in the dark will not turn blue-black because of absence of starch.
In conclusion, the iodine is used to test for starch.

So healthy people get them to try and build immunity against said vaccine. Like if you have the flu, your body is fighting. In the Flu vaccine parts of the flu are in the vaccine to help your body learn to become immune. So option C.
Sorry if this is confusing, hope it helps!
Explanation:
<u>Seed Dispersal is an adaptive mechanism in all seed-bearing plants, participating in the movement or transport of seeds away from their parent plant to ensure the germination and survival of some of the seeds to adult plants. There are many vectors to transport the seed from one place to another.</u>
