Energy Flow and Trophic Levels

Each day the sun provides the light energy that is the driving force for most of Earth’s ecosystems. However light energy is not evenly distributed to all points on Earth. The intensity and duration of light that strikes any point on the Earth’s surface varies with latitude and season.

The lack of evenly distributed light is partially responsible for seasons, climatic diversity & consequently ecosystem diversity and biodiversity.

Most of the solar energy that streams towards Earth is reflected back into space by the atmosphere.

Most of the solar energy that streams towards Earth is reflected back into space by the atmosphere. Of the small amount that gets through the atmosphere, much of it is filtered by the ozone layer.

Most of the solar energy that streams towards Earth is reflected back into space by the atmosphere. Of the small amount that gets through the atmosphere, much of it is filtered by the ozone layer. Of the small amount that is able to get through the atmosphere, most is reflected back into space off the oceans’ surfaces.

Of the small amount that is able to get through the atmosphere, most is reflected back into space off the oceans’ surfaces. To support life on Earth, the most important light energy that makes its way to the Earth’s surface is in the red and blue portion of the spectrum.

Plants and algae are organisms that have the ability to collect light energy and convert it into a storable form. To do so they produce glucose through a metabolic process called photosynthesis. Glucose is a storable form of energy. Most plants store it as starch but a few store it directly as glucose.

I need someone to tell me the formula or components for photosynthesis.

CO2 + H2O

CO2 + H2O C6H12O6 light

CO2 + H2O C6H12O6 During photosynthesis plants use carbon dioxide and water molecules as the source of carbon, hydrogen, and oxygen atoms that will be necessary to manufacture glucose molecules. light

CO2 + H2O C6H12O6 + O2 During photosynthesis plants use carbon dioxide and water molecules as the source of carbon, hydrogen, and oxygen atoms that will be necessary to manufacture glucose molecules. Because water and carbon dioxide supply more oxygen atoms than are needed to make glucose, some will be left over. This oxygen forms diatomic oxygen molecules (O2) that are released as a waste product into the air by the plant. light

Leaves are the primary photosynthetic surface area of most plants.

Organisms obtain their energy by either producing their own or by eating others.

Organisms obtain their energy by either producing their own or by eating others. The levels in a food chain at which organisms obtain energy are called trophic levels.

CO2 + H2O C6H12O6 + O2 Any organism that produces its own food, either photosynthetically or chemosynthetically, is referred to as a producer.

Some organisms consume plants and take their nutrients and energy directly from them.

Such organisms are called primary consumers (C1). They are also known as herbivores.

Primary consumers are often eaten by other animals. These are secondary consumers (C2).

Tertiary consumers (C3) eat secondary consumers.

Animals that eat tertiary consumers are called quaternary consumers (C4).

Trophic levels higher than C4 are referred to by number. This roadside hawk is a C5. Snakes are an important part of its diet.

Scavengers, tear off bits and pieces of dead organisms and ingest them. Decomposers, on the other hand, live in or on the dead organism. They secrete enzymes that digest the organism externally, then absorb the nutrients through their cell membranes.
