They study their behavior, feeding habits, interaction with other organisms, their role in the ecosystem, mating behavior, etc.

The non-living things a marine biologist study are physical and chemical environment of marine habitat, geology of the area, concentration of salt, and other molecules that affect marine biology.

What is entomophily?

It is a method of performing cross-pollination where the transfer of the pollen grains from the anther of one flower of a plant to the stigma of another flower of a plant happens by the insects.

It is often called insect pollination. The flowers that are pollinated by insects have attractive petals of bright colours. This adaptation ensures that the insects will be attracted to the flowers.

The nectar present in these flowers, on which the insects feed is also sweet with an attractive scent. This is another factor which attracts the insects to the flowers.

It is by way of sucking the nectar that the insects also get pollen stuck on their mouth regions and legs. The pollen grains produced by these flowers are also sticky.

Therefore, to examine if monarchbutterflies prefer a specific coloured flower, different plants with different coloured flowers need to be used and the colour of the flowers will be the variable.

What is the benefit of using a shortcut in a reaction between two chemicals

The benefit of using a shortcut in a reaction between two chemicals is that sings of a chemical change will still be found. We will still get a new substance and its chemical and physical properties will differ from those of the original substance.


I hope it helps, Regards.

A reaction with a shortcut would yield more chemical output.
