Because per capita birth and death rates do not change in response to the size (or density) of the population, this model is said to be density-independent.
Can you please go over this some more during class??

Conservation biologists want to understand both types because this helps them manage populations and prevent extinction or overpopulation.
I think it's always interesting when it comes to the topic of overpopulation. It feels wrong that we have to kill a certain amount of animals, if there are no predators in a given area, but it's something that needs to be done for the population to be at a functional level.

N, is plotted over time, a J-shaped growth curve is produced (Figure 6.3.16.3.1\PageIndex{1}).
we are looking over this graph in bio, but I am still very confused. Will you provide extra problems to practice?

One of the most productive ecosystems on earth, wetlands have water present at or near the surface of the soil or within the root zone, all year or for a period of time during the year, and the vegetation there is adapted to these conditions. Wetlands are instrumental for the maintenance of clean water and erosion control. Microbes and plants in wetlands absorb nutrients and in the process filter and purify water of pollutants before they can enter coastal or other aquatic ecosystems.
I think process itself shows the importance of emergent properties.

Recent studies suggest that natural processes may slow the rate of increase of carbon dioxide in the atmosphere, but it is doubtful that either the earth's oceans or its forests can absorb the entirety of the extra carbon released by human activity
In my biology class, we have learned that oceans are a big factor for absorbing heat, however, it has been obviously noted that the oceans have been warming up way too much leading to ocean acidification and killing off biomes such as coral reefs, wouldn't these occurrences be an indicator that the oceans can no longer absorb the extra carbon release and heat? How much better can this be communicated to countries and companies that are large contributors of carbon?

The theory of natural selection stems from the observation that some individuals in a population are more likely to survive longer and have more offspring than others; thus, they will pass on more of their genes to the next generation.
I think it's interesting that sometimes frequencies just happen, and do not need to be accurate for the next population to survive. Has this ever happened to any known species ?

I think it's interesting that populations have to adapt and go through evolution together, rather than individually. But I wonder if there have been occasions in which virus/bacteria populations evolve individually? or is that completely different.
-
So is this saying that some adaptation is error?

A large part of science turns out to be serendipity—luck and chance—capitalizing on chance and doing something with it.
As someone who struggles with perfectionism and overthinking, it brings me a lot of peace of mind knowing that a hypothesis never has to be perfect.
Question: Are there limits to what one can experiment with?
