- Plant kingdom is composed of multicellular autotrophs.
- The statement that science demands evidence is proofed by the fact that Scientists rely on historical data or on experimental
Further Explanation:
Every single moment an individual is live, needs energy. Even an individual is in resting position requires energy. An individual get energy by having food. An organism is divided into two categories on the basis of their process of attaining food are:
Organisms that are autotrophs in nature can make their own food. Mainly plants are referred as autotrophs but there are other examples of autotrophs are also present. Algae, phytoplankton, bacteria and plants, are photosynthetic in nature. They use sunlight to make sugar, which then converts into energy. They make their food by photosynthesis. Photosynthetic organisms are mainly green because they contain a chlorophyll pigment which helps in absorbing light.
Organisms that are heterotrophs are depending on other for their food. They do not make their own food. Heterotrophs also referred as herbivores that mainly eat plants. The number herbivores are less in ecosystem than autotrophs because they get only ten percent of energy from autotrophs. Some examples of heterotrophs are animal and fungi. Bacteria, archae, eukarya and protista are examples of heterotrophs as well as autotrophs.
Experimental findings are the accurate observations that are derived several cycles of experiments. Thus, these are the accurate evidence that favors a hypothesis. Also, predefined data contribute to the finding of experimental evidence.
