1. How does the equations help explain the role of
faltersainse [42]

Answer:

1. Producers create energy for other organisms to consume.

2. It converts sugars to usable energy that all organisms need

Explanation:

All living organisms require energy, which they obtain by feeding on one another in an ecosystem. The series of feeding steps involved is called FOOD CHAIN. Food chain always starts with an organism called PRODUCER, which is an autotroph i.e. capable of producing its own food by using light energy from sunlight e.g plants. All other organisms in the food chain are directly or indirectly dependent on plants to get energy. This is because plants and other autotrophs create the energy that is being transferred as the food chain progresses.

2. Cellular respiration is an important phenomenon for all living organism because it is the metabolic process by which they obtain the usable energy by their cells i.e. ATP. Food molecules in form of sugar (glucose) eaten by organisms are broken down in the presence of oxygen (aerobic) to yield ATP molecules, which is the energy currency of every living cell. This energy is used to perform the organism's life activities.

How is a tissue different from an organ? How are they similar?
nikklg [1K]
A tissue is different from an organ because an organ is made up of a group of tissues working together to do a specific job. While an organ is made up of cells that are working together to do a specific job.

They are similar by both of them working together to accomplish specific functions.

Just in case, an example of an organ is a heart.
hope this helps
