Humans are biotic components of marine ecosystems and have a significant impact on the maintenance of healthy, well-balanced ocean ecosystems. Ecosystems can be classified into three main scales.Micro: A small scale ecosystem such as a pond, puddle, tree trunk, under a rock etc.Messo: A medium scale ecosystem such as a forest or a large lake.Biome: A very large ecosystem or collection of ecosystems with similar biotic and abiotic factors such as an entire Rainforest with millions of animals and trees, with many different water bodies running through them.

In recent years, the red panda population has dropped significantly, leading conservation groups to classify it as a vulnerable or endangered species. While rain only falls occasionally, water is often stored in succulent plants and accumulates under covered areas as well. Desert animals, or xerocoles, perspire less and fulfill their maximum percentage of water requirements through the food they eat.

Ecology essentially focuses on how living organisms interact with their environment. The living and physical components are linked together through nutrient cycles and energy flows. It is these overlapping scales that give them their spectacular colours and patterns. Grasslands were developed during the Cenozoic era about 65.5 million years ago. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Ask: How could this impact coastal ecosystems? Ephemeral salt lakes are common throughout the southern sector. Although abiotic factors have been less important to date, changing temperatures could cause further habitat loss in the future.
