A student sets up an experiment and wants to see if different amounts of fertilizer affect the growth of basil. They place 4 sep

arate plants in 4 same-sized pots. Each pot receives the same soil, the same amount of light, and the same amount of water. They add no fertilizer to Pot 1, 10g of fertilizer to Pot 2, 20g to Pot 3, and 50g to Pot 4. What are the fixed variables in this experiment?
POT 1
soil, light, water, type of plant
amount of fertilizer

Answer:

pot size, soil, amount of light, type of plant, amount of water.

Explanation:

The fixed variables would be the pot size, soil, amount of light, type of plant, and amount of water.

There are three variables in a research experiment:

  • fixed variables
  • independent variables
  • dependent variables

<em>The fixed variables in an experiment are those variables whose values are kept constant throughout the course of the experiment. They are also referred to as controlled variables.</em>

<em>Independent variables are the actual variables being measured during an experiment.</em>

<em>The dependent variables are the variables being tested during an experiment.</em>

The fixed variables are kept constant so as to be able to measure the effects that the independent variable will produce on the dependent variables during an experiment.

<u>Hence, in this case, the fixed variables would be  the pot size, soil, amount of light, type of plant, and amount of water; the independent variable would be amount of fertilizer and the dependent variable would be a growth-determining factor.</u>

rusak2 [61]

Answer:

Interspecific competition

Explanation:

Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.

The graph given shows the growth of the relative population size of two different species grown together.

It shows that P. aurelia, with time, outcompetes P. coudatum.

This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.

P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.

Interspecific competition beats describes the relationship between the two species in graph B.
