Parasitism occurs when one organism is harmed and the other is benefited, like a leach sucking blood.
Mutualism occurs when both organisms are benefited. Secondly, there’s commensalism, in which one is benefited and the other is unaffected. Finally, there is parasitism.
Hello class! Today I will be talking about different ecological relationships. First is mutualism.
Next, I will teach you all about the threats to biodiversity. Of course, you must understand what biodiversity is, first. Biodiversity is the difference between organisms, species, and ecosystems.
Another threat is pollution. There are two main ideas within pollution, and these include biomagnification and the combustion of fossil fuels
One of the threats to biodiversity is habitat loss. An example could be deforestation, in which trees are being cut down to make room for other structures or plants.
Biomagnification is the process of toxins being increased as trophic levels increase. The combustion of fossil fuels contributes to a large amount of CO2 in the air, which is slowly destroying our atmosphere.
Another threat is the threat of invasive (or exotic) species. If a nonnative species is introduced to the environment, then there will be no natural predators to suppress that population.
Overexploitation, another threat to biodiversity, occurs when humans gather or hunt too much of one organism, pushing it to near-extinction. Lastly (for threats, anyways), is the act of habitat fragmentation. This occurs when humans build roads or other structures through ecosystems, making room too small for large animals.
Kids, this is Mr. Hardwick and his classroom. Say hi! He is an expert of sustainability of biodiversity.
Hey y’all! As you can tell, I take a lot of pride in my beard! Anyways, sustainability of biodiversity means to preserve the natural ways of life, and to keep as many species alive as possible. No, Jimmy, not spices.
One way to do this is to use bioremediation. This is where bacteria are employed to break down certain chemicals, like an oil spill. This will help clean up areas much faster.
Oh, class! I almost forgot to tell y’all this! Every species has a carrying capacity, which means that they will eventually run out of organisms to have. The species and the ecosystem cannot have any more numbers of population! The human population is supposedly capped at 10 million! Isn’t that incredible?! Well, I hope you all enjoyed this lecture! See you next time, everyone!
