DENDROLOGY

Detailed explanation-1: -Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.

Detailed explanation-2: -The first order consumers or primary consumers are always herbivores since they feed on the producers directly. Autotrophs are organisms that produce food using nutrients from the soil and sunlight and are also called producers.

Detailed explanation-3: -Plants and algae (plant-like organisms that live in water) are able to make their own food using energy from the sun. These organisms are called producers because they produce their own food.
