When we think about the life of plants it is difficult to imagine without interaction with the animals, as they establish different symbiotic relationships day after day. These symbiotic relationships include all the herbivores, or in the contradictory way, all the carnivorous plants. But there are what are some mutualism relationships in the tropical rainforest other super important interactions between plants and animals, such as the relationships that allow them to help each other and to live together.
So, this time I want to present mutualism between plants and animals. And, what is mutualism? This relationship increase their biological effectiveness fitnessso there is a tendency to live always together. According to this definition, how to keep dating casual pollination and seed dispersal by animals are cases of mutualism.
Many plants are visited by animals seeking to feed on nectar, pollen or other sugars they produce in their flowers and, during this process, the animals carry pollen from one flower to others, allowing it reaches the stigma in a very effective way. Thus, the plant gets the benefit of fertilization with a lower cost of pollen production, which would be higher if it was dispersed through the air. And the acid and base examples list, in exchange, obtain food.
Therefore, a true relationship of mutualism is stablished between the two organisms. The extreme mutualism occurs when the species evolve depending on the other organism, i. We define the coevolution such as these evolutionary adaptations that allow two or more organisms to establish a deep relationship of symbiosis, due that the evolutionary adaptations of one specie influence the evolutionary adaptations of another organism.
But there are many other plants that also have co-evolved with their pollinators, as a fig tree or cassava. In no way, this should be confused with the trickery produced by some plants to their pollinators, that is, when they do not obtain any direct benefit. For example, some orchids can attract their pollinators through odours pheromones and their curious forms that resemble female pollinator, stimulating them to visit their flowers.
The pollinators will be impregnated with pollen, which will be transported to other what are some mutualism relationships in the tropical rainforest due to the same trickery. The origin of seed dispersal by animals probably had occurred thanks to a co-evolutionary process between animals and mechanisms of seed dispersal in which both plants and animals obtain a profit. This process could have intensified the diversification of flowering plants angiospermssmall mammals and birds during the Cretaceous MA.
The mutualism can occur in two ways within the seed dispersal by animals. The first case is carried out by animals that eat seeds or fruits. These seeds or some parts of the fruits diaspores are expelled without being damaged, by defecation or regurgitation, allowing the seed germination. In this case, diaspores are carriers of rewards or lures that result very attractive to animals.
That is the reason why fruits are usually fleshy, sweet and often have bright colours or emit scents to attract them. For example, the red-eyed wattle Acacia cyclops produces seeds with elaiosomes a very nutritive substance usually made of lipids that are bigger than the own seed. What is the meaning of income tax in hindi in return, the rose-breasted or galah cockatoo Eolophus roseicapillus transports their seeds in long distances.
Because when the galah cockatoo eats elaiosomes, it also ingest seeds which will be transported by its flight until they are expelled elsewhere. And the other type of seed dispersal by animals that establishes a mutualistic relationship occurs when the seeds or fruits are collected by the animal in times of abundance and then are buried as a food storage to be used when needed. As long as not all seed will be eaten, some will be able to germinate. Plants of the genus Cecropia live in tropical rain forests of Central and South America and they are very big fighters.
The strategy that allow them to grow quickly and capture sunlight, avoiding competition with other plants, resides in the strong relationship they have with Azteca ants. Plants provide nests to the ants, since their stems are normally hollow and with separations, allowing ants to inhabit inside. Furthermore, these plants also produce Müllerian bodies, which are small but very nutritive substances rich what are some mutualism relationships in the tropical rainforest glycogen that ants can eat.
In return, the ants protect Cecropia from vines and lianas, allowing them to success as a pioneer plants. Ant Plants: Cecropia — Azteca Symbiosis www. Few years ago, an interesting plant has been discovered in Cuba. This plant is pollinated by bats, and it has evolved giving rise to modified leaves that act as satellite dish for echolocation performed by these animals. That is, their shape allow bats to locate them quickly, so they can collect nectar more efficiently.
And at the same time, bats also pollinate plants more efficiently, as these animals move very quickly each night to visit hundreds of flowers to feed. In general, we see that the life of plants depends largely on the life of animals, since they are connected in one way or another. For this reason, we can say that life of some animals and some plants resembles a marriage.
