A line graph has a vertical axis labeled "Average plant mass (g)^ * and a horizontal axis labeled "Herbicide (g/plant)." What in

SSSSS [86.1K]

Answer:

The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.

Explanation:

As the vertical axis is labelled as average plant mass, it will make the y- coordinate.

As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.

The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.

10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.

Hence, Dis the correct option.

Which statement describes both scavengers and detritivores

NeTakaya

Scavengers are an organism that mostly consumes decaying biomass.

Detritivores feed on decaying organic matter and return essential nutrients back to the ecosystem.

So the answer would be (D). Both organisms feed on pieces of other dead organisms.

The answer is; B is younger than D

In sedimentary rocks, the bottom layers are older that overlaying layers. This is because sediments are placed on top of each other by surface runoffs to ocean beds. Therefore, the first sediments to be deposited will always be towards the bottom as more and newer ones are brought in and deposited.

sergeinik [125]

Answer:

1. Mutualism

2. Mutualism (it was previously thought to be a case of commensalism)

3. Predation

4. Competition

Explanation:

1. Zooxanthellae and hard coral - Mutualism

These two organisms live in symbiosis. This means that both benefit each other. Zooxanthellae allow corals to gain energy through photosynthesis and, in turn, they receive important nutrients that are produced during the metabolism of the hard coral.

2. Remora and manta ray - Mutualism

Remoras and manta rays benefit each other. Remoras attach to manta rays mainly for transportation and feeding, but they also do it for protection. In turn, they make sure manta rays are clear from harmful bacteria and parasites. Several years ago, it was thought that manta rays didn't gain any benefit from remoras, so this was thought to be a case of commensalism. However, research has shown that they both benefit from each other. Therefore, this is also a case of mutualism.

3. Tiger shark and green sea turtle - Predation

In some areas (not everywhere) tiger sharks feed upon green sea turtles. For example, in Hawaii, have been observed to attack green sea turtles and feed on them. Researchers have spotted numerous sea turtles with characteristic tiger shark bites.

4. Dolphins and school of trevallies - Competition

Trevallies are large species of fish that feed on small schools of fish like dolphins. They both have their own predatory strategies that involve planning and gathering to catch large amounts of fish. Therefore, trevallies and dolphins compete for small schools of fish.
