Ecology: Ecological Pyramids

Easy

(Originais Teachy 2023) - Question Easy of Biology

In an aquatic ecosystem, an ecological pyramid of energy is built to represent the energy relationship between different trophic levels. Considering a lake as an example, the first trophic level is composed of phytoplankton, which are primary consumers, followed by zooplankton, which feed on phytoplankton, and finally, fish that feed on zooplankton. Suppose that 10,000 Joules of solar energy are captured by the phytoplankton every day. Of these, 1,000 Joules are used in their own respiration and other metabolic functions, and 9,000 Joules are available for the transfer of energy to the next trophic level. The zooplankton, which feeds on phytoplankton, consumes 1,800 Joules of energy from the phytoplankton and uses 900 Joules for its own energy needs. To build the ecological pyramid of energy, follow the instructions: 1. Calculate the energy transfer efficiency between phytoplankton and zooplankton. 2. Graphically represent the ecological pyramid of energy for the three mentioned trophic levels, using a scale of 1 cm for every 1,000 Joules of energy. Make sure to include the quantities of energy available and consumed at each trophic level. Justify the importance of the ecological pyramid of energy in understanding trophic relationships and in planning conservation and management strategies for aquatic ecosystems.

In a genetics experiment, a Biology teacher challenged his 3rd-year high school students to analyze a pea plant that exhibits two characteristics: seed color and seed texture. Seed color can be yellow (AA or Aa) or green (aa), and seed texture can be smooth (TT or Tt) or wrinkled (tt). These characteristics are determined by genes on different chromosomes, so they segregate independently, following Mendel's 2nd Law. The teacher challenges the students to determine the expected phenotypic and genotypic ratios in the F2 (second generation) of a cross between two plants that are heterozygous for both characteristics. Additionally, he asks the students to relate the concept of independent assortment to Mendelian inheritance principles. Based on this information: 1. Calculate the expected phenotypic and genotypic ratios in the F2 of the proposed cross. 2. Explain how the independent segregation of alleles for each characteristic relates to Mendel's 2nd Law and how this principle influences the determination of ratios in the F2.

The tissues of the human body perform specific functions and are organized into systems that ensure the organism's homeostasis. Imagine that a scientist, while studying the effects of a disease that affects skeletal muscle tissue, observed that, as a result of the disease, the contraction capacity of the muscle fibers was compromised. Based on this situation, describe: 1) The relationship between the structure of muscle fibers and their contractile function, including the main cellular components involved in this process. 2) Explain how a change in a tissue such as skeletal muscle can affect the functioning of other systems in the human body, considering the interdependence between tissues and systems for the maintenance of health.

In an experiment with Drosophila melanogaster, a researcher observed that the gray-bodied fly (gene A) and short wings (gene B) were frequently inherited together, while the black-bodied fly and long wings were also commonly observed together. After crosses and analyses, the researcher concluded that genes A and B demonstrate a pattern of linkage and that the recombination frequency between them is 10%. What is the definition of linkage and how can the recombination frequency between genes A and B be used to determine the genetic distance between them in centimorgan map units (cM)?
