Roundworms are segmented worms that evolved after the Cambrian Explosion over 575 million years ago. They can live in a variety of environments, including in the ocean, on land, and as parasites inside other living organisms. Common roundworms that infect humans and animals include Ascaris, which lives in the intestines, and Trichinella, which is contracted by eating undercooked meat. Roundworms play important roles in ecosystems by decomposing organic matter and recycling nutrients. They have adapted to survive in nearly any environment and can enter a dormant state when conditions are unfavorable. Signs of roundworm infection include coughing, abdominal pain, and the presence of worms in vomit or stool
Behaviour is a phenotypic expression of the interaction of the genotype (of individuals or species) with the environment. This expression evolves from the stimuli that motivate animals to an inborn activity, such as the sucking response of the calf upon contacting the teat of the cow, or a learned or practiced activity, such as coital attempts by inexperienced bulls and the competent performance of the experienced bulls.
Man observes behaviours of animals and infers a cause or reason. Such inference must derive from a full knowledge of the behaviour and of the variability of the behaviour of species — a knowledge that is gained after much work and over an extended time. Interestingly, man's observations and inferences are species-specific behaviours which also have a variability in performance. Man's evolution from the hunter behaviours to the recent husbandry behaviours must have involved much change in concepts, namely a revolution in behaviour and perceptions. Man is presently in a state of evaluating again his relationship to other species of animals in respect of his perceptions of animal welfare and the ethology of animal life.
In our mysterious world of nature, animals depend on one another, in terms of food, shelter and even transportation. This form of dependence is named symbiosis. One form of symbiosis is commensalism. Let us explore the concept of commensalism together!

I own a 75 gallon, saltwater fish tank. In that tank we have fish, crabs, shrimp, snails and corals. In order to keep these creatures alive and growing, its important to have the correct lighting, temperature and food source.
Zooplankton
plays an important role in keeping an aquarium healthy.
Zooplankton
; whose name drives from a Greek word meaning "drifter", are small floating organisms that drift around in water current. Corals, mussels and various other filter-feeders eat
zooplankton
.
Zooplankton
are eaten by small fish, which are then eaten by bigger fish, as the chain continues.
Zooplankton
have three major groups;
crusacea
,
rotifers
, and
protozoas
. All play an important role in fresh and saltwater ecosystems.
Zooplankton
measure between two micrometers and up to 8 inches in
length
. Some z
ooplankton
have adapted mechanisms to deter fish from eating then. They have adapted things like transparent bodies, bad tastes, and
cyclomorphosis
; which allows them to release chemicals into the water to signal other
zooplankton
that predators are nearby.
Most
zooplankton
are herbivores and eat phytoplankton and algae. Others species of
zooplankton
eat the parasites of larger animals, such as fish.
Zooplankton
are sensitive to temperature changes, oxygen depletion, toxic chemicals, and other environmental issues. Because of this, scientists can use them as first indicators of environmental quality and ecological changes on our planet. Though small, these tiny creatures bridge the gap between algae and bigger organisms. Many of today's creatures in our planets oceans wouldn't grow and/or survive if it weren't for

One animal organism that I found interesting was the species of multicellular Nematodes.
Nematodes are the most plentiful multicellular animals on the planet. They are everywhere; in soil and on decomposing material, from the cold environments to the tropics, in all plant life, in almost all animals, including humans, and also insects (“Information”, 2016).
Nematodes are non- segmented roundworms that possess complete digestive, excretory, nervous and reproductive systems (“Information”, 2016). Most are microscopic. The diversity of nematode forms and territories are incredible: there are more than 15,000 known species, can you imagine that! They infect everything from bugs to whales to humans. Nematodes can take the energy of living organism and cause serious diseases, even kill humans and animals. There are other nematode parasites in humans that are transmitted by eating meat that is not cooked adequately, or through contact with soil or water contaminated with feces, from humans or animals (Hay, 2016).
The nematode organism known as”
Wuchereria bancrofti
”
can cause damages to the lymphatic system and causes debilitating inflammations in different parts .

The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

2. Classification Scheme Roundworms is a phylum in the LinneanTaxonomic Hierarchy. These modifications include the addition of more taxa and the appliance of cladistics to decide the classification of an organism.
3. 575 million years ago… Round worms evolved after the Cambrian Explosion. They evolved into segmented worms. Round worms are very closely related to Flatworms which evolved the same time around round worms did. Round Worms Flat Worms
4. Where do Roundworms live? Roundworms started off living in oceans, but as they evolved more, they started to spread out in many places. There are many different roundworms around the world. Places may include in the ocean, on land, or even inside living things. They are sometimes preferred as parasites.
5. Common roundworms Roundworms are the most parasites found in people infected with parasite diseases. They are in the human or animal skin for blood. They usually enjoy moist, warm areas where an infection can thrive. Free-living roundworms recycle decaying rotting organic matter in almost all environments.
6. Decomposing and Consuming Roundworms could be either decomposers or consumers. Without roundworms, organic matter would not be decomposed and the energy supply to plants and animals would be reduced. Roundworms allows minerals and nutrients vital to plants and other organisms to be recycled from bacteria, fungi and decaying organic matter and returned to the soil.
7. RINGWORMS Ringworms are the typical organism in the roundworm family. This is a fungal infection. They usually occur in raw meat from an animal or poor hygiene practices. This picture illustrates a face greatly affected by this organism.
9. ADAPTATIONS The roundworms have adapted to almost every environment. They can be found living on, in or around nearly every living organism in virtually every habitat. They also are able to go into a state of cellular hibernation when their habitat is less desirable. They also can adapt deep in the soil on the ground. They feed on many plants.
