A forest fire took over this forest ecosystem, burning a majority of the trees in the area. How would this forest fire impact different two different consumer populations in this ecosystem?
Answer:
Herbivore and carnivores.
Explanation:
This forest fire greatly affected two consumer populations such as herbivores and carnivores because herbivores has no food available due to forest fire. The unavailability of food for the herbivores leads to the decrease in herbivore population that also adversely affected the population of carnivore ( those organisms that feed on herbivores) so both are affected from the forest fire.

What are two ways to identify NESW?
Answer:
-The sun
-shadow
Explanation:
-The sun rises in the general direction of east and sets in the general direction of west every day, so you can use the location of sunrise or sunset to get an approximate idea of direction.
-The shadow will always move - or, more precisely 'grow' in the west-to-east direction. (Before noon, when the sun is rising, the shadow will grow shorter and after noon when the sun is setting, the shadow will grow longer)

two shark populations utilize the same fish population as their main food source
algae blooms decrease as the number of fish increase
lack of sunlight due to changes in the seasons restricts the growth of certain plants
plentiful oxygen leads to an increase in the number of reefs
Answer:
A. two shark populations utilize the same fish population as their main food source
I'm guessing this is from Marine Biology. I know this is an example of competition because two different groups of sharks are eating food from the same source. If one group gets to it first every time, they could leave the other group with no food. So it is a competition.
Answer:
two shark populations utilize the same fish population as their main food source

Rough-skinned newts produce a strong toxin called TTX as a defense mechanism against predators. Garter snakes can
tolerate a very limited amount of the toxin. However, several populations of garter snakes have recently shown an
increased tolerance for TTX. The different populations of snakes have independently acquired a gene variation that
allows them to better block the effects of the toxin.
