Food energy can be defined as the chemical energy derived from food people and animals consume. In this sense, human beings and animals must eat food to acquire the energy necessary for the body's healthy functioning. Without food, the body uses up the stored glucose as energy and later ...
Some living things need sunlight to make food. Animals need oxygen to produce energy for their bodies. The environment must also have the right tcperature for organisms to survive. Without these non-living things, life would not exist (存在). Just like abiotic factors make it possible for ...
All living organisms need energy in order to live, and for most, this energy comes from the sun. Organisms are categorized as either heterotrophs or autotrophs, based on how they get their energy.Answer and Explanation: Organisms that are not autotrophs must either consume or absorb their ...
All of these organisms work to balance the population of organisms within the compost, which increases the efficiency of the entire process. Making Compost To start making compost, you need to first choose a site and then start adding your ingredients. Yifei Fang/Getty Images Making compost ...
Without the sun, plants can't get the food they need to grow, reproduce and survive. Unlike animals, plants are autotrophs, meaning they create their own food source. They use energy from light or from the sun, water and gases from the air to create glucose. This process is photosynthes...
Plants in particular need to have a very efficientimmune systemfor two important reasons. Firstly, they sit at the bottom of thefood chainso there are a lot ofopportunisticorganisms out there, including insect herbivores and microbial pathogens who want to tap into that biochemical energy that is...
It provides us with enough water,food,sunshine,mineral and so on.I can even say we can only live in the earth . There may isnt any celestial body like earth that our human can live .But there is only one earth in the world,so please protect it ,protect our "mother",we can do it...
Animals see differently – from simple eyes that only tell the difference between light and dark, to complex eyes that can see colours and depth perception.
According to Hullian drive theory (Hull, 1943), organisms only behave for the satisfac- tion of a biological or physiological need, proposing that S–R habits must be fueled by the reduction of a biological drive to have a behavioral effect. Modern motivation theo- ries abandoned the drive ...
Moreover, changes in landscape structure and microhabitats will affect the morphology of organisms through the link between morphology and performance (Arnold 1983). Selection on heritable variation or plastic responses may result, but survival will depend on the speed of the morphological change ...
