Sphinxa [80]

Options for the question have not been given. They are as follows:

type of soil

type of plants

exposure to sunlight

method for measuring the growth

Answer:

exposure to sunlight

Explanation:

A scientific experiment has an experimental group and a control group. Control group is included to omit any error in results due to the factors other than the variable factor. Experimental group is the one exposed to different levels of the variable factor.

Here, Carlo wants to determine the the effect of day length on plants' growth. The test variable here is thus the duration of sunlight. In experimental group, this duration will be changed to determine its effect. In control group it will be kept constant so that results from other factors can be excluded from the observed experimental result.

Can anyone give a help with this please I have to submit it tomorrow!!
Usimov [2.4K]

Answer:

Q.1: I can't help you with this, sorry :(

Q.2: Seaweed is the producer because it takes energy from the water and sun in thermal reactions.

Q.3: Phytoplankton is the second-order consumer because they eat first-order consumers.

Q.4: Whelks and crabs because they eat limpets, which eat producers, and they also eat seaweed.

Q.5: Gulls are carnivores because they eat the crabs, and so are crabs because they eat mullets

Q.6: Limpets and lobster would become less populated, but not yet endangered. Gulls would starve and probably disappear from this ecosystem.

Q.7: Whelks' numbers would decrease because of the number of lobsters consuming them, but then lobsters would starve because of the decline in their food. Then this would repeat, shaking the whole ecosystem.
