    Study Notes

    Ichthyology and Ecology

    • Ichthyology deals with the study of fish characteristics.
    • Ecology studies the relationships between living organisms and their environments.

    Biology Concepts

    • Living organisms can be categorized based on their ecological roles, particularly as herbivores which eat only plants and algae.
    • Producers, primarily plants, form the base of the energy pyramid.
    • Herbivores are consumers that directly feed on producers and obtain significant energy.

    Plant and Animal Differences

    • Plant cells uniquely possess a cell wall, unlike animal cells.
    • Animals are classified based on their body covering; mammals have fur, while reptiles like lizards have dry scaly skin.

    Ecosystem Interactions

    • Commensalism benefits one species without affecting another, while parasitism harms the host.
    • Competition arises when two organisms, like owls and hawks, vie for the same prey.

    Reproduction and Genetics

    • Parthenogenesis is a form of reproduction where eggs develop without fertilization.
    • Mitosis results in the duplication of chromosomes, which are organized into homologous pairs in diploid cells.

    Food and Diet

    • Autotrophs, or producers, can synthesize their food, contrasting with other organisms like amoebas, which are unicellular.
    • Carbohydrates include sugars and starches, with sources excluding meat.

    Nutritional Science

    • Key elements essential for human survival include nitrogen, hydrogen, oxygen, and carbon.
    • Vitamins like niacin are crucial for physiological functions.

    Environmental Science

    • The water cycle encompasses evaporation, precipitation, and runoff processes.
    • The nitrogen cycle influences mushroom growth post-lightning due to atmospheric nitrogen.

    Climate Change and Pollution

    • Human activities contribute to increased methane and carbon dioxide levels, driving climate change.
    • Acid rain results from sulfur emissions combined with atmospheric water, impacting ecosystems negatively.

    Energy and Metabolism

    • Metabolism defines the process of converting food into energy, essential for maintaining life functions.
    • Caloric content in food indicates the energy that can be derived from it.
