Our big beautiful blue planet is in a complicated balance of life and death, predator and prey friend and foe the word ecology literally translates to the study of home our home planet Earth.

What’s ecology? and Ecology definition

The more specific definition of ecology is the study of the relations of organisms to one other and to their physical environment, it answers questions like how do living things interact and rely on each other or on their surroundings?  The survival of any species is dependent on other living organisms and non-living components, this is called interdependence, for example, humans could not survive without plants to produce oxygen, and the plants need carbon dioxide from humans, and other organisms or even from volcanic eruptions.

Ecological complexity definition

Ecology is extremely complex and difficult to study, so one way that colleges deal with this complexity is to use ecological models to represent or describe the components of an ecological system, this model is called an ecosphere the largest ecological system we know of is the biosphere planet Earth, this is the only biosphere we study because so far it’s the only place in the universe that we know has life, the biosphere is the thin veil on earth that goes from above the ground to the deepest parts of the ocean, all life on earth is in the biosphere if you zoom into one ecosystem it’s a little easier to see all the parts working together.

What is an ecosystem

An ecosystem is all the organisms and non-living environment found in a particular place, the living things in this pond ecosystem include fish, turtles, aquatic plants, algae, insects, birds, and bacteria. These organisms interact in ways that affect their survival, for instance, insects and fish and aquatic plants and the turtles eat the fish, the non-living or physical and chemical things, include the chemical composition of the pond, its pH, its levels of dissolved oxygen, and carbon dioxide, and its supply of nitrogen, which all help to determine what kinds of organisms live in the pond, and how abundant they are a community, is all of the interacting organisms in an area, it does not include the nonliving factors.

definition of biosphere

A population is all of the organisms of one type of species in the area, and an organism refers to an individual animal in order the levels of organization from the most broad to the narrowest are the biosphere ecosystem community population and organism when we talk about where, an organism lives instead of saying ecosystem, which might still be a fairly large area, we could talk about its habitat it’s just a word that means the place where an organism’s lives. A hot includes both biotic and abiotic factors, biotic factors are the Living parts of the habitat and when you add the letter “A” in front of the word it means not living, so abiotic factors are the nonliving parts of the habitat using the pond ecosystem, as an example biotic factors include: glasses, algae, fish, birds, and insects, the abiotic factors include: the pH of the water, rocks, soil, the sunlight, and temperature.

Habitat and the word Niche

Now you may sometimes hear people try to use the word habitat and the word niche interchangeably and that’s not quite how they should be used a niche, is the job or role of the organism within its environment, so habitat is a home, and niche is a job, for example a redwood-tree takes energy from the Sun and turns it into sugar using photosynthesis, redwood-trees are often found in foggy coastal areas like Santa Cruz California, the habitat is the foggy coastal areas like California, and the niche is converting the sun’s energy into sugar by photosynthesis.

Generalists and specialists

Now some organisms feel very broad niche and some very specific, one generalists eat a variety of foods, and specialists eat few or even just one type of food, pigs are an example of a generalist, they’ll eat lots of different foods very happily, this can be beneficial to them because they could survive on a variety of foods and fill a niche in many different habitats, the panda on the other hand is a specialist, because they only eat bamboo, bamboo is unavailable the panda population may die off this species, has a much higher risk of becoming extinct so it’s often beneficial for organisms to be generalists.

    There are a few interesting points with time in the following paragraphs but I don’t know if these center to heart. There’s some validity but I most certainly will take hold opinion until I look into it further. Great post , thanks and then we want more! Put into FeedBurner likewise
