Hope this helps ;)

Answer:

Macronutrients are defined as those nutrients that supply the body with calories (Protein, Fat, Carbohydrates).

Micronutrients are those nutrients that the organism needs in smaller amounts than Macronutrients (Vitamins are Minerals in humans and animals and Minerals in plants)

Explanation:

The nutrients are divided into two catogories, which are:

A. Macronuetrients.

B. Micronutrients.

Below you can find the definition of each one of them:

A. Macronutrients are defined as those nutrients that supply the body with calories, that's why the body needs them in large amounts.

There are three Macronutrients. These are:

1. Protein.

2. Fat.

3. Carbohydrates.

B. Micronutrients are defined are those nutrients that the organism needs in smaller amounts than Macronutrients.

In humans and animals Micronutrients are also known as "Vitamins and Minerals". They are essential to keep us alive, because they mantain the metabolic and physiological function of our organism.

Inr plants, Micronutrients are all minerals and are essential for plant growth.

How do flowering plants reproduce by fertilization if they are immotile?Fertilization takes place in their roots.
O They conjugate with plants nearest them.
Insects and other organisms carry pollen to other flowers.

Answers

Immotile flowering plants accomplish fertilization with the help of Insects and other pollen from organisms that carry pollen to other flowers.

Explanation:

The transfer of pollen from anther to the stigma of flower is called pollination.
Pollination is of two types: a) Self pollination b) cross-pollination
Transfer of pollen from anther to the stigma of same flower or flower of same plant is called self pollination.
Transfer of pollen from anther to the stigma of different plant is called Cross-pollination.
Pollination is the process by which angiosperms carry out sexual reproduction.
Since, plants are immobile they need some agents for pollination like, insects birds, wind, water etc
