A chemical compound that cells use to store and release energy, it is a necessary energy source for all forms of biological work.

Name given to organisms that produce their own food from inorganic compounds.

Autotrophic organisms that use sunlight to generate their own food are called:

Process formed by three steps, glycolysis, the kreb cycle and the electron transport chain.

They are the sum of chemical reactions that occur within a cell, being synthesis or degradation.

Name given to the cellular organelle where the photosynthesis process occurs.

What are the energy-carrying molecules that are formed in light-dependent reactions.

What carbohydrate is the one that is obtained at the end of the independent reactions of the light or Calvin Cycle.

It allows organisms to live with little or no oxygen, in places such as deep water, soil, and the digestive tract of animals, including humans.

It is a complex set of multiple factors that surround and affect the health, performance, abundance, survival and diversity of living things.

It is the set of populations of different species that coexist in a particular place and that maintain interactions with each other.

It is an open system made up of biotic communities and their abiotic environment, which maintain an exchange of matter and energy.

They are environmental factors that affect levels of ecological organization.

The resources that living beings require such as water, mineral nutrients, carbon dioxide, oxygen, solar radiation and the energy contained in the chemical bonds of certain molecules are called:

It is a linear diagram that indicates from which organism to which organism the food energy moves, or which organism eats which one.

It is the set of food webs intertwined with each other, and it is the way in which populations are effectively related in an ecosystem.

They are cyclical patterns in which different elements such as carbon, nitrogen, phosphorus and water move within the biosphere:

The fraction of energy (and biomass) fixed by photosynthesis and that is invested in the tissues is called:

Name given to the energy stored in the tissues of organisms.

It establishes that when passing from one trophic level to another, only 10% of the energy obtained in the previous level is obtained. This means that only 10% of the total consumed is stored in its structure to be used by the next trophic level.

In nature, each species fulfills a particular role and this role within a community or ecosystem is defined as:

It refers to the average state of the atmospheric conditions, which characterize a region in a long period of time (at least 30 years).

Interaction between two populations where the effect is positive for one and negative for the other (plus-minus)

Interaction between two populations where the effect is positive for one and negative for the other (plus-minus)
