What are some of the ecological conditions that are necessary for human life to continue on Earth?

Living things obviously need water to survive they also need food to have energy. Air is another main thing, not all living organisms need oxygen though. Homeostasis. The ability to maintain homeostasis, equilibrium in the inner processes of an organism, is vital to the perpetuation of life.

∙ 11y agoFor Life to Exist on an Earth-like Planet, here are a few things we know:
Planet must be in a solar system that's in the right location in the galaxy (The Goldilocks Zone).
System cannot be too close to gaseous clouds in the arms.
System cannot be too close star clusters.
System cannot be too close to red giants.
Planet must be in a solar system with larger planets.
Planet must be the right diameter.
Planet must have water.
Planet must have the right mass.
Planet must have a magnetic field.
Planet must have the right kind of atmosphere.
Atmosphere must be self cleaning and regenerative.
Atmosphere must be transparent yet shielding.
Planet must have tectonic plates.
Planet must have the right type of star to orbit.
Planet must have the right size of star to orbit.
Planet's orbit must be nearly circular around the star.
Supporting planets orbits must orbit in the same plane.
Planet must be the right distance from the star.
Planet must have a moon.
Moon must be the right distance from the planet.
Moon must be the right size.
Moon must orbit the planet in a regular cycle.
Planet must have a tilt that's stabilized.
Planet must have the right rotation speed.
Planet must have the right kind of elements.
Planet must have an iron core to produce a magnetic field.
These are but a few. Take any one of them away.....NO LIFE as we know it.
Note:
The above requirements describe what is necessary to have a second Earth. But the possibility of life existing on less Earth-like planets is certainly not excluded. A planet capable of supporting an oxygen-atmosphere at temperatures allowing liquid water is possible without a Luna-like moon, and might even be possible without tectonic plates. Furthermore, rocky planets able to support life could be moons orbiting a Jovian-type planet; this would vastly extend the range of the distance between star and planet, since Jovian-type planets can generate and radiate their own heat. Many more combinations of conditions exist that could result in habitable worlds.

2 water
3 sunshine

∙ 13y agooxygen, food, water are the most necessary but you would also need a nice home or shelter. Health is also important

What is Earth's major ecological communities?
biome
Why is the entire earth called the largest ecological system?
Because the whole planet is an ecological system, everything else is just a subsystem.
How does water make earth the living planet?
Water is necessary for life to exist, and since earth is the only planet known to have liquid water, it is the living planet
Earth's necessary materials are called what?
Resources.
Are weather conditions cause by the sun earth and air?
Mostly by earth itself

What is ecological importance of Halley's Comet?
Halley's Comet is unlikely to ever pose a hazard to the Earth. As such, it has no ecological significance.
What are the conditions necessary for a total eclipse of the Sun?
In a solar eclipse, the Sun, the Moon and the Earth line up almost exactly so that the shadow of the Moon falls on the Earth.
Use ecological footprint in a sentence?
An ecological footprint is a measure of human demand on Earth's ecosystem. An example sentence would be: She recycles because she wants her ecological footprint to be small.
Why are decomposers necessary for the continuation of life on Earth?
Decomposers are necessary for the continuation of life on earth because decomposers break down dead organisms and give the nutrients back to the plants so they can continue to grow, which provides food herbivores, which feeds the carnivores, and so on.
If the present greenhouse effect trend continues into the year 2100 earths annual average temperature could?
Due to the Greenhouse Effect, Earth's temperature is continually rising. If the trend does not change, the Earth's annual temperature will continue to rise, causing significant ecological problems.
Why is the entire earth called the largest ecological system?
Because the whole planet is an ecological system, everything else is just a subsystem.
What are the incidents of ecological backlashes?
THE incedent of backlashes is about of our earth because the air pollution)
Positive roles ecological balance of the earth?
yes it can but it depends on plate techtonics
What is the Ecological Importance of the giant Panda?
It is important because it keeps the earth in balance
How does conserving energy tie into your ecological footprint?
It ties into your ecological footprint because if you start conserving energy you will have lesser measure on the human demand on the Earth's ecosystems.
