OBJECTIVE FORESTRY

Detailed explanation-1: -Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.

Detailed explanation-2: -Explanation: Autotrophs are organisms that can synthesize food from inorganic sources. Autotrophs are the only producers in the food chain. In addition to plants and some bacteria, algae and fungi are autotrophs.

Detailed explanation-3: -The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl).
