Why is water so important to living organisms? Why does the body need fat? Why do we need scientific ethology? Why is water so important for life? Why are all living things on Earth carbon-based? Why, chemically, is nitrogen not more available to living things?
Some protection from radiation, such as being on a rock, seems to help organisms survive the journey. But wherever they land, these space travelers need an environment that will allow them to live and grow. So with these ideas in mind, is it fair to say that we humans might be aliens?
Aquatic organisms need DO to survive, so that's why some water bodies have artificial aeration. Examples include a paddle wheel or a fountain in the middle of a pond, the use of an air stone in an aquarium, and pumping air into aeration basins at wastewater treatment plants to sustain mic...

Why are nutrients important to living organisms? Why do dogs eat paper? What happens when a bug's exoskeleton breaks? Why do animals live in forest habitats? Why do cats eat their own vomit? Why do herbivores need nitrogen? Why are plants autotrophs?
How and why the first nervous systems evolved remain deep, unanswered questions. Because nervous systems likely emerged around 560 million years ago (Budd and Jensen2017), we must rely on indirect information from fossils and extant organisms to infer when and how neuron-based integrative systems ...
One very common group of organisms seen in mulch and mistaken for fungi are the slime molds. They are not related to fungi, but do develop spores and have a mobile (plasmodium) phase where they can be seen to slowly move from one spot to another. Eventually, when the plasmodial stage is...
(carbon containing) waste and break it down into its simplest parts. This produces a fiber-rich, carbon-containinghumuswith inorganic nutrients like nitrogen, phosphorus and potassium. The microorganisms break the material down throughaerobic respiration. All that really means is they need oxygen. ...
How do plants get the nitrogen they need to grow? How do plants control tropisms? How do annual plants reproduce? How do some plants develop poisonous berries? How do conifers grow? Why is the seed an important plant adaptation? What determines which plants grow where?
As living organisms, our bodies have many different physical needs that must be met in order for us to live and survive. For example, we need energy in order to fuel our bodies, and we must receive regular sleep. Answer and Explanation: ...
