The correct answer is (4) Autotrophic organism.
Green plants make their own food by the process of photosynthesis using sunlight. Most of the autotrophs use carbon dioxide, sunlight and carbon dioxide to produce glucose that is used by the plants to obtain energy. Most of the oxygen comes from these organisms and decrease in the number of green plants can lead to several problems due to decrease in the amount of oxygen. Example: green plants, algae, and even some bacteria. This food and oxygen is produced by the action of autotrophic organisms
The reason why a dichotomous key to identify organism is valuable, is because it helps you classify organisms,it helps you identify eco -systems, it helps you analyze an organism's traits.
Explanation:
A dichotomous key is a skill that has been brought about by scientists, to help people to identify and classify organisms.
In Dichotomous key, the main way of identifying an object is by it scientific name.This is because, though two objects might look similar to each other but they might belong to a whole different species.
So, it is is easier to identify the organism from its scientific name, as it will tell us which species it belongs to.
This key is very useful to people who are novice, and don't know much about identifying an organism.
This key also helps identifying, whether an organism belongs to a particular closely related group of organisms or is a separate organism.
It helps one analyze the traits of an organism, and based on their characteristics, it will help you identify and classify the species of the object or organism.
