ESS - Species and Population
Storyboard Text
- Amensalism is the one animal gets affected and one does not get bothered like cat and rat. Mutualism is both animals get benefit like crocodile and bird. Commensalism is one gets benefit and one does not get bothered like sucker fish on sharks. Competition is both animals fights like birds and squirrels fight for nits. Parasitism is one gets benefit and the other gets affected like ascaris and tape worm in human digestive tract. Herbivory is animal eating plants. Predation is -
- Ugh! Why won't he leave me be
- I can't believe you brought your ESS textbook to our trip, lil bro!
- Did you know that ecology can be separated into species, habitat, population and niche!
- Ugh not ESS again !
- S-curve starts with exponential growth, no limiting factors affect it at first but the rate slows down above certain population size that cause a constant size of population. J-curve is population grows exponentially at first then collapses, diebacks, exceeding capacity on long -term before collapse occurs , overshoot
- Yes I know! Species are organisms that share common characteristics,habitat is the environment where species live, population is species that live in the same area determined by factors of sizes, and niche is how an organism makes a living that can be abiotic and biotic factors
- Come sit with me, I'll tell you about what I learned yesterday during ESS class !
- So, fundamental niche is the full range of resources that species can survive and reproduce. Realized niche describes the actual due to biotic interactions. Limiting factors are factors that slow doen growth. Carrying capacity is the maximum number of species that can live in an area
- Of course I know better !
- Biotic factors are the producers, consumers, detritivores and decomposers. Like, this racoon beside me, the bacteria in the racoon, and the plants around us. While the abiotic factors are the non-living components. Like, theair, river and soil
- Ugh he disturbed my explanation !!
- Predation is gets benefit and the other gets affected like lion predatory on deer
- Intraspecific competition is competition between same species but interspecific competition is between different species. S and J curve describes a generalized population to conditions, abiotic and biotic factors.
- Looks like you do know something about ESS !
