Thermal pollution is defined as sudden increase or decrease in temperature of a natural body of water which may be ocean, lake, river or pond by human influence. This normally occurs when a plant or facility akes in water from a natural resource and puts it back with an altered temperature. Usually, these facilities use it as a cooling method for their machinery or to help better produce their pollen
Answer:
Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic. In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution. For example, the bones in the wings of bats and birds have homologous structures (Figure 1).
Figure 1. Bat and bird wings are homologous structures, indicating that bats and birds share a common evolutionary past. (credit a: modification of work by Steve Hillebrand, USFWS; credit b: modification of work by U.S. DOI BLM)
Notice it is not simply a single bone, but rather a grouping of several bones arranged in a similar way. The more complex the feature, the more likely any kind of overlap is due to a common evolutionary past. Imagine two people from different countries both inventing a car with all the same parts and in exactly the same arrangement without any previous or shared knowledge. That outcome would be highly improbable. However, if two people both invented a hammer, we can reasonably conclude that both could have the original idea without the help of the other. The same relationship between complexity and shared evolutionary history is true for homologous structures in organisms.
Answer:
the producers would get the most then the primary consumers then the top consumers
Answer:
A hummingbird feeding: Mutualism
Explain Interaction: The hummingbird drinks the nectar from the flower and the hummingbird may help pollinate the flower.
I'm a bit confused by the plants on the floor one.
Plants on a Forest Floor: Competition
Explain Interaction: The plants on the forests floor compete with each other for the same resources. Both may not receive enough of those resources. Note: When I was around Middle School and High-school I was only taught mutualism, commensalism, and parasitism, so let me know if competition is not a choice your teacher gives you to choose from or wasn't taught to you
Flea bites human: Parasitism
Explain Interaction: The flea drinks the persons blood as food and the person is hurt. Flea bites can be itchy and become painful. Fleas may also also carry disease.
Clownfish in Anemone: Mutualism (although I hear some people say commensalism)
Explain Interaction: The anemone provides protection and a place to live for the clownfish. The anemone may eat bits of food left over from the clownfish.
