Fragmentation
the worms break apart and each part grows a new head or tail by regeneration.
Answer:
The correct answer would be predation.
Predation is one of the types of ecological interactions which take place in an ecosystem.
In this interaction, one organism kills or hunts another organism to feed upon it.
The organism which kills or hunts is termed as predator, for example, Venus flytrap is a predator.
The organism which gets hunted or killed is termed as prey, for example, the insect is prey in this case.
Answer:
Light was a limiting factor for photosynthesis under the given conditions. Light is required for photosynthesis.
Explanation:
According to Blackman's principle of limiting factors, the rate of photosynthesis is regulated by the factor which is present below the minimal value. Photosynthesis is regulated by many factors such as CO2 concentration, temperature, light intensity, etc. However, under particular conditions, the factor present below the minimum levels regulate its rate.
In the experiment, when the light intensity was present below its minimum levels, an increase in the light intensity increased the rate of photosynthesis. Here, light intensity was the limiting factor and no other factors such as CO2 or temperature would affect the rate of photosynthesis.
Once the light intensity reaches its optimal levels, other factors become limiting and there is no further increase in the rate of photosynthesis by increasing the light intensity.
D. Eating foods full of sodium, salts, fats and sugars can contribute to all of these.
The answer is: Abscisic acid.
