An ecological pyramid is a graphical representation of the relationship between the different living organisms at different trophic levels. Explain the three ecological pyramids in detail. What are the shortcomings of each type's ecological pyramids in the study of ecosystem?

Ecological pyramids are also referred to as energy pyramids, and they are of three major types.

Three types of ecological pyramids:

- Pyramid of number includes the number of organisms in each trophic level, and the pyramid is upright.

- Pyramid of Biomass includes the amount of biomass produced at each trophic level, and the pyramid is upright except for oceans.

- Pyramid of energy includes productivity of the biomass at each trophic level, and the pyramid is always upright.

Shortcomings:

- The same species may belong to two or more trophic levels.

- It assumes a simple food chain while we have only complex food webs in nature.

- Saprophytes are not included in the pyramids.

- Variations in season and climate are not included.

A new vaccine was tested to see if it could prevent the ear infections that many infants suffer from. Babies about a year old were randomly divided into two groups. One group received vaccinations, and the other did not. The following year, only 328 of 2460 vaccinated children had ear infections, compared to 508 of 2453 unvaccinated children.
Complete parts a) through c) below.
a) Are the conditions for inference satisfied?
A. Yes. The data were generated by a randomized experiment, less than 10% of the population was sampled, the groups were independent, and there were more than 10 successes and failures in each group. B. No. It was not a random sample. C. No. The groups were not independent. D. No. More than 10% of the population was sampled.

What is the optimal time for a scuba diver to be on the bottom of the ocean? That depends on the depth of the dive. The U.S. Navy has done a lot of research on this topic. The Navy defines the "optimal time" to be the time at each depth for the best balance between length of work period and decompression time after surfacing. Let

What is meant by the term “90% confident” when constructing a confidence interval for a mean? a. If we took repeated samples, approximately 90% of the samples would produce the same confidence interval. b. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean. c. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean. d. If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples.
