Explanation:

The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still USE the traditional DIVISION into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychaetes. Annelids are CONSIDERED members of the Lophotrochozoa, a "super-phylum" of protostomes that also INCLUDES molluscs, brachiopods, flatworms and nemerteans.

The basic annelid FORM consists of multiple segments. Each segment has the same sets of organs and, in most polychates, has a pair

ALGAE - Algae - Classification of algae: The classification of algae into TAXONOMIC GROUPS ... the classification of land plants, but the organization of groups of algae above the ORDER level

ANSWER:

In biology, taxonomy (from Ancient GREEK (taxis), meaning 'arrangement', and -(-nomia), meaning 'method') is the science of NAMING, DEFINING (circumscribing) and classifying groups of biological organisms on the BASIS of shared characteristics.

There is a process to explain this,

As we know about ecosystem, defined as the structural and functional unit of nature made by the combination of biotic and abiotic i.e., living and non-living organisms respectively.These are interlinked with each other.

as, Biotic(living) =>producer,consumer,

decomposer.

and Abiotic (non-living) =>light, temp,

water, soil, air.

These are depending on each other.

as, there is a CHAIN,

Plants=>Insect=>Small Fish =>Large fish

=> decomposes by decomposer.

Plants =>convert SIMPLE organisms

into complex organisms. Decomposer=>convert complex organism

into simple organisms.

So, we can say that the large fish is a complex organism which TAKES there food like from simple organism like sun or plants.

That's why we can say that complex organism EVOLVED from simple organisms.

TRANSPIRATION is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a SMALL amount of water TAKEN up by the roots is used for GROWTH and metabolism. The remaining 97–99.5% is lost by transpiration and GUTTATION.

Explanation:

cadatum is a microscopic, unicellular PROTOZOAN. Its size ranges from 170 to 290um or up to 300 to 350um. SURPRISINGLY, paramecium is visible to the NAKED eye and has an elongated slipper like shape, that’s the reason it’s also referred to as a slipper animalcule.

The posterior end of the body is pointed, thick and cone-like while the anterior part is broad and blunt. The widest part of the body is below the middle. The body of a paramecium is ASYMMETRICAL. It has a well-defined ventral or oral surface and has a convex aboral or dorsal body surface.
