makvit [3.9K]

Answer and Explanation:

The steps of the scientific method are

1) A question the investigator wants to answer.

2) Antecedents or Previous knowledge about the study object.

3) The goal, which is what the investigator wants to know.

4) The hypothesis that the investigator makes in order to predict what is going to happen.

5)The experiment is performed to answer the question.

6) Results achievement

7) Conclusions where the hypothesis is rejected or accepted.

In the case of the exposed example,

  1. Question: How does the amount of sunlight affect the extent of flower production?
  2. Previous knowledge and antecedents about solar radiation influencing different plant growth and flowering. Information about the species of interest. Other studies or investigations performed in relation to this question.
  3. Objective/Goal: To study the influence of sunlight in flowering
  4. Hypothesis: Too many hours of radiation affect flowering production
  5. Experiment: (Example)

Native species are going to be planted in the garden to observe their growth and flower production at different exposure levels to sunlight. Native species will be planted, as they are used to the environmental conditions and they do not need extra care, as a cultivated species would. More than one individual is needed to ensure their establishment. All the species will be watered according to each species needs and location. Plagues will be equally controlled.

  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives straight sun radiation during the whole light hours.  
  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives sun radiation during half a day
  • 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a  shaded section.

Plants will be grown and the flowering process will be recorded by season in relation to the number of flowers, sizes, quality, and pollinizer visitors which will reflect the amount and quality of nectar.

6 y 7. Every recorded result will be then analyzed to conclude.

Explain why there is a limited number of organisms in a food chain
tankabanditka [31]
There are different trophic levels at each stage. Trophic levels determine the amount of energy at each stage of the food chain. For example, the energy is 100% at the producer (plant), so it's the 1st trophic level, and so on. Energy amounts decrease as you go up a food chain, and you rarely find more than 5 animals in one because there is not enough energy left for the 6th consumer
