When individuals live together, their collective behavior has a larger, meta-effect on the environment, quickly entangling the population into the larger ecological web that sustains their habitat.

The actions of an individual can have far-reaching effects. Behavioral ecology seeks to understand how individual organisms behave in their social and geophysical environment, and in turn, how the behaviors of the individual effect the world around them.

A brief introduction to ecology, including the relationship between  organism & physical environment, the relationships between organisms, and the geochemical nutrient cycling that sustains the biosphere.

The viruses are pathogenic conglomerations of biomolecules, existing somewhere in the ambiguous void between true life, and unliving physical chemistry. Some say the viruses are not alive, others say they are the oldest branch on the tree of life...

The animals are dynamic biochemical superstructures; they are mobile food-processing tubes, equipped with a variety of appendages and morphologies adapted to a particular habitat & ecological niche.

The fungus are the quiet decomposers, playing a critical role in the recycling of biomatter. Without fungus to break down dead biomass and return those nutrients to the wild, the biosphere would collapse.

The plants are photosynthetic organisms, capable of turning the raw energy in sunlight into biological chemicals, which then sustains the entire food chain with carbon & nutrients.

The protista are a diverse group of organisms, including both single celled and multicellular species. From an evolutionary perspective, they are the bridge between bacteria, and complex macroscopic life.

A brief introduction into the diversity of life, beginning with the oldest lineages on Earth; the Archaea & Bacteria.

In the presence of Human development and pollution, and extreme climate change, what does the future hold for the evolution of Earth life?
