which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths. Because they interact with light to absorb only certain wavelengths‚ pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis. In plants‚ algae‚ and cyanobacteria‚ pigments are the means by which the energy of sunlight is captured for photosynthesis. However‚ since each pigment reacts with only a narrow range of

Rizal Technological University Investigatory Study (Kingdom Animalia) Written by: Rodette Joyce Laurio Submitted to : 1 Introduction In biology‚ kingdom is a taxonomic rank‚ which is either the highest rank or in the more recent three-domain system‚ the rank below domain. Kingdoms are divided into smaller groups called phyla (in zoology) or divisions in botany. When Carl Linnaeus introduced the rank-based system of nomenclature into biology‚ the highest rank was given the name

There are many factors that account for the changes to the vegetation over time within ecosystems in the British Isles‚ such as human activity‚ climate‚ soil‚ light availability and intensity and natural disasters. The characteristics of the vegetation that are influenced by these factors are height‚ distribution‚ variety of species‚ adaptations and density of the vegetation. Some of these factors have relatively little influence on the succession development‚ whereas others have a dramatic influence

Chelydra serpentine belongs to the kingdom Animalia because they are multicellular and eukaryotic heterotrophs. They also belong to the phylum Chordata because they had the following features at some point in their lives: pharyngeal slits‚ dorsal nerve cord‚ notochord‚ post-anal tail. Chelydra serpentine have waterproof skin covered in scales‚ are ectothermic and have hard shelled eggs that are water proof. These features make them a part of the class Reptilia. They belong to the order Testudines

them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than their reflection of light is their ability to absorb certain wavelengths. Because pigments interact with light‚ they are very useful to autotrophs. These pigments help the user gain energy. Because pigments only absorb a narrow range of light‚ many different color pigments are needed to capture more of the sun’s energy. There are three basic classes of pigments which are chlorophylls‚ carotenoids
