The relationship between humans animals and plants

Prev Next Just how different are we to our four-legged friends? Zoologist, Professor Alex Kacelnik University of Oxford talks about the ways in which other animals are more similar to humans than perhaps we might like to admit… More Everyone has read stories about animals performing amazing acts of intelligence, bravery and loyalty - the kind of qualities you might only usually associate with humans.

The relationship between humans animals and plants

Commensal mites travelling phoresy on a fly Pseudolynchia canariensis Commensalism describes a relationship between two living organisms where one benefits and the other is not significantly harmed or helped. It is derived from the English word commensalused of human social interaction.

It derives from a medieval Latin word meaning sharing food, formed from com- with and mensa table. Examples of metabiosis are hermit crabs using gastropod shells to protect their bodies, and spiders building their webs on plants.

Parasitism Head scolex of tapeworm Taenia solium is adapted to parasitism with hooks and suckers to attach to its host. In a parasitic relationshipthe parasite benefits while the host is harmed. Parasitism is an extremely successful mode of life; as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi.

Moreover, almost all free-living animal species are hosts to parasites, often of more than one species. Mimicry Mimicry is a form of symbiosis in which a species adopts distinct characteristics of another species to alter its relationship dynamic with the species being mimicked, to its own advantage.

Batesian mimicry is an exploitative three-party interaction where one species, the mimic, has evolved to mimic another, the model, to deceive a third, the dupe.

In terms of signalling theorythe mimic and model have evolved to send a signal; the dupe has evolved to receive it from the model.

This is to the advantage of the mimic but to the detriment of both the model, whose protective signals are effectively weakened, and of the dupe, which is deprived of an edible prey.

For example, a wasp is a strongly-defended model, which signals with its conspicuous black and yellow coloration that it is an unprofitable prey to predators such as birds which hunt by sight; many hoverflies are Batesian mimics of wasps, and any bird that avoids these hoverflies is a dupe.

Amensalism is an asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other. Competition is where a larger or stronger organism deprives a smaller or weaker one from a resource.

Antagonism occurs when one organism is damaged or killed by another through a chemical secretion. An example of competition is a sapling growing under the shadow of a mature tree. The mature tree can rob the sapling of necessary sunlight and, if the mature tree is very large, it can take up rainwater and deplete soil nutrients.

Throughout the process, the mature tree is unaffected by the sapling.

Indeed, if the sapling dies, the mature tree gains nutrients from the decaying sapling. An example of antagonism is Juglans nigra black walnutsecreting juglone, a substance which destroys many herbaceous plants within its root zone. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed.

Whilst the presence of the weevil has almost no influence on food availability, the presence of ibex has an enormous detrimental effect on weevil numbers, as they consume significant quantities of plant matter and incidentally ingest the weevils upon it.

Cleaning symbiosis Cleaning symbiosis is an association between individuals of two species, where one the cleaner removes and eats parasites and other materials from the surface of the other the client. Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fishnotably wrasses but also species in other genera, are specialised to feed almost exclusively by cleaning larger fish and other marine animals.The photograph, which was taken in Kafue Elephant Orphanage, Zambia, reveals what the relationship between our species and these majestic animals ought to look like..

The human race as a whole has. Published: Mon, 5 Dec Human, animals and plants are created to have a good relationship with each other to make a better and beautiful life.

Without animals and plants, human cannot eat anything and probably we cannot live anymore. This tree diagram shows the relationships between several groups of organisms.

Without animals and plants, human cannot eat anything and probably we cannot live anymore. The domestication of animals is the mutual relationship between animals with the humans who have influence on their care and reproduction. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors.

He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits. The relationship between the plants and animals is called symbiotic relationship. Which means that both are dependent on each other.

For example, the plants give off oxygen which the animals.
