SpeciesBasic unit of taxonomic classification, below genusThe hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown.A species (pl. species) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.OrganismAn organism is any living thing that functions as an individual. Such a definition raises more problems than it solves, not least because the concept of an individual is also difficult. Several criteria, few of which are widely accepted, have been proposed to define what constitutes an organism. Among the most common is that an organism has autonomous reproduction, growth, and metabolism. This would exclude viruses, even though they evolve like organisms.
PhysiologyPhysiology (; from Ancient Greek (phúsis)'nature, origin' and (-logía)'study of') is the scientific study of functions and mechanisms in a living system. As a subdiscipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out chemical and physical functions in a living system.

CopepodCopepods (; meaning 'oar-feet') are a group of small crustaceans found in nearly every freshwater and saltwaterhabitat.
BacillusBacillus, from Latin "bacillus", meaning "little staff, wand", is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.
CrustaceanCrustaceans (from Latin word "crustacea" meaning: "those with shells" or "crusted ones") are mandibulatearthropods that are traditionally a part of the paraphyleticsubphylumCrustacea (). Crustaceans are mainly aquatic, including decapods (shrimps, prawns, crabs, lobsters, and crayfish), seed shrimps, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp.
Natural environmentThe natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity.
PollutionPollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
BehaviorBehavior (American English) or behaviour (British English) is the range of actions of organisms, individuals, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.
Body of waterAny significant accumulation of water, generally on a planet's surfaceThe Aubach, a watercourse in GermanyA fjord (Lysefjord) in Norway.A body of water is a significant accumulation of water on the surface of the earth. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles.
Quantitative researchQuantitative research is a research strategy that focuses on quantifying the collection and analysis of data. It is formed from a deductive approach where emphasis is placed on the testing of theory, shaped by empiricist and positivist philosophies. Associated with the natural, applied, formal, and social sciences this research strategy promotes the objectiveempirical investigation of observable phenomena to test and understand relationships.*As an Amazon Associate I earn from qualifying purchases.
