Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
Producers are organisms that capture sunlight from the sun to make organic food. Consumers are animals and get food by consuming other organisms. Decomposers break down all dead organisms from a soil bacterium part of the food cycle. Detritivore feed on organic matter. Producers get their food from the sun. And compete with all organisms above them on the food pyramid. A food chain is a cycle pathway of life, relationships among organisms is a mutualism that results in energy. Most energy is lost as metabolic heat, the total heat, and energy wast. Meaning that each level only receives 10% of the energy in the level
