• producers contain chlorophyll & can______

Explanation:

Ecology is the study of the relationships between living organisms and their environment. Abiotic factors are non - living components of the environment that affect living organisms. Biotic factors are living organisms in an environment. A habitat is the place where an organism lives, and a niche is the role an organism plays in its ecosystem. Energy in an ecosystem flows from producers (which make their own food) to consumers (which eat producers or other consumers). Sunlight is the main energy source for most life on earth, and producers can perform photosynthesis using chlorophyll.

Answer:

• What is Ecology? The study of the relationships between living organisms and their environment.
• It explains how living organisms affect each other and the environment they live in.
• The Non - living Environment: Abiotic factors are non - living components of the environment.
• Abiotic factors affect an organism's survival and distribution.
• The Living Environment: Biotic factors are living organisms in an environment.
• All organisms depend on others directly or indirectly for food, shelter, etc.
• What is a Habitat and a Niche? Habitat is the place where an organism lives. Niche is the role an organism plays in its ecosystem.
• Energy Flow: Energy in an ecosystem flows in a one - way direction.
• Energy is transferred from producers (make their own food) to consumers (use food by eating producers or other consumers).
• Producers: Sunlight is the main energy source for most life on earth. Producers contain chlorophyll & can perform photosynthesis.
