Best answer: What is the direct source of energy for zebras?

The zebra obtains energy by eating grass. The process by which a cell captures energy in sunlight and uses it to make food is called photosynthesis (foh toh SIN thuh sis).

Does a zebra obtain energy from the Sun directly or indirectly?

The zebra and lion both obtain the sun’s energy indirectly, from the energy that the grass obtained through photosynthesis. Plants manufacture their own food through the process of photosynthesis.

What is the direct source of energy for each organism?

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

How do animals get energy?

Animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.

What is a direct source of energy used in photosynthesis?

Energy from the Sun fuels life on Earth

Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.

How do zebras obtain energy?

The zebra obtains energy by eating grass. The process by which a cell captures energy in sunlight and uses it to make food is called photosynthesis (foh toh SIN thuh sis).

What captures energy from sunlight?

Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.

What is the direct energy source for the Calvin cycle?

Overview of the Calvin cycle

In the Calvin cycle, carbon atoms from CO2​start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.

Which of the following is the direct source of energy for living cells?

In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (Figure 1).

What is the direct source of energy used by the light independent reactions?

After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms.

What is the main source of energy for animals?

The primary source of energy for animals is carbohydrates, primarily glucose: the body’s fuel. The digestible carbohydrates in an animal’s diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions. Adenosine triphosphate, or ATP, is the primary energy currency in cells.

What is the main source of energy for the carnivore?

Because animals cannot produce energy directly from the sun, they must eat plants or other animals that eat plants, and acquire energy, either directly or indirectly, from glucose. Animals that eat plants exclusively are called herbivores. Animals that only eat meat are called carnivores.

How do animals use sugars as sources of energy?

A primary role for the glucose molecule is to act as a source of energy; a fuel. Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be ‘burnt’ in the cytoplasm and mitochondria to release carbon dioxide, water and energy.
