Electrons are stripped from water in the light reactions of photosynthesis. Light provides the energy to excite electrons.

ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.

A neuron or nerve cell is a cell that carries electrical impulses. Neurons are the basic units of the nervous system and its most important part is the brain. Every neuron is made of a cell body (also called a soma), dendrites and an axon. Dendrites and axons are nerve fibres.

The gap between two communicating neurons is termed Synaptic cleft.

Genes which are segment of DNA of a cell contains instructions for assembling proteins.

A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers.

Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.

Tertiary consumers often occupy the top trophic level, and so are predated by no other animals; in this case they are called "apex predators". However, when they die their bodies will be consumed by scavengers and decomposers.

Consume foods that have the most nutrition for their kcalories describes the Nutrient Density.
