    It is also the study of - ProProfs

    It is also the study of

    • Plants

    • Animals

    • Aquatic organisms

    • Fishes

    Correct Answer
    A. Aquatic organisms
    Explanation
    Aquatic organisms refer to any living organism that resides in water, including plants and animals. The study of aquatic organisms involves understanding their behavior, habitat, and ecological interactions within aquatic ecosystems. This field of study helps scientists and researchers gain insights into the diversity, adaptations, and conservation of aquatic life forms. By studying aquatic organisms, we can better understand the intricate relationships between different species and their environment, and develop strategies to protect and sustain these vital ecosystems.

    A community of living organisms in conjunction with the nonliving components of their environment interacting as a system is - ProProfs

    A community of living organisms in conjunction with the nonliving components of their environment interacting as a system is

    • Ecosystem

    • Network

    • Population

    • Interaction

    Correct Answer
    A. Ecosystem
    Explanation
    An ecosystem refers to a community of living organisms, such as plants, animals, and microorganisms, that interact with each other and with the nonliving components of their environment, such as air, water, and soil. This interaction creates a complex system where energy and nutrients are exchanged, and various ecological processes take place. Therefore, an ecosystem is the most appropriate term to describe a community of living organisms in conjunction with the nonliving components of their environment interacting as a system.

    Hydrobiology studies life processes in - ProProfs

    Hydrobiology studies life processes in

    • Soil

    • Sand

    • Water

    • Air

    Correct Answer
    A. Water
    Explanation
    Hydrobiology is the study of life processes specifically in water. It focuses on the organisms that live in water bodies, their interactions, and the ecological processes that occur within aquatic environments. This field of study examines various aspects such as the biology, ecology, and physiology of aquatic organisms, as well as the water quality and its impact on these organisms. Therefore, the correct answer is water.

    Dead organic matter are broken down by - ProProfs

    Dead organic matter are broken down by

    • Producers

    • Actors

    • Decomposers

    • Eaters

    Correct Answer
    A. Decomposers
    Explanation
    Decomposers are organisms that break down dead organic matter into simpler substances, such as nutrients, that can be recycled back into the ecosystem. They play a crucial role in the decomposition process by breaking down complex organic compounds into simpler forms through the process of decay. This decomposition is essential for nutrient cycling and the overall health of the ecosystem. Producers, on the other hand, are organisms that produce their own food through photosynthesis or chemosynthesis. Actors and eaters are not relevant terms in the context of breaking down dead organic matter.

    Low oxygen conditions are referred to as - ProProfs

    Low oxygen conditions are referred to as

    • Hypoxia

    • Oxygen

    • Supply

    • Erosion

    Correct Answer
    A. Hypoxia
    Explanation
    Hypoxia is the correct answer because it refers to low oxygen conditions. It is a condition where there is a decrease in the amount of oxygen available to the body's tissues. This can occur due to various reasons such as high altitudes, respiratory diseases, or certain medical conditions. Hypoxia can have serious consequences on the body's organs and functions, leading to symptoms like shortness of breath, confusion, and even organ failure in severe cases. Therefore, hypoxia accurately describes the condition of low oxygen levels.

    Flowing water is termed - ProProfs

    Flowing water is termed

    • Hydro

    • Ocean

    • Sea

    • Lotic

    Correct Answer
    A. Lotic
    Explanation
    Lotic refers to flowing water, such as in rivers or streams. It is used to describe the movement and characteristics of water in these environments. The other options, hydro, ocean, and sea, do not specifically refer to flowing water but rather to bodies of water in general. Therefore, lotic is the correct answer as it is the term used to describe flowing water.

  • 8. 
     The enrichment of a water body with nutrients is - ProProfs

     The enrichment of a water body with nutrients is

    • Erosion

    • Fertilization

    • Nutrienting

    • Eutrophication

    Correct Answer
    A. Eutrophication
    Explanation
    Eutrophication refers to the process of a water body becoming enriched with nutrients, particularly nitrogen and phosphorus. This enrichment leads to excessive growth of algae and aquatic plants, which can disrupt the balance of the ecosystem. It is often caused by human activities such as agricultural runoff, sewage discharge, and the use of fertilizers. This process can result in decreased oxygen levels in the water, leading to the death of fish and other aquatic organisms.

    Biotic and abiotic components are linked together through - ProProfs

    Biotic and abiotic components are linked together through

    • Nutrient cycle

    • Flow

    • Water

    • Network

    Correct Answer
    A. Nutrient cycle
    Explanation
    The biotic and abiotic components are linked together through the nutrient cycle. This cycle involves the movement and exchange of nutrients between living organisms and their environment. Nutrients such as carbon, nitrogen, and phosphorus are taken up by plants from the soil, then passed on to herbivores when they consume the plants. These nutrients are further transferred to carnivores when they consume herbivores. Decomposers break down dead organisms and release the nutrients back into the environment, completing the cycle. This interconnected process ensures that nutrients are constantly recycled and available for all organisms in an ecosystem.

    Still waters are called - ProProfs

    Still waters are called

    • Lentic

    • Stream

    • Flowing

    • Lake

    Correct Answer
    A. Lentic
    Explanation
    Still waters are called lentic because the term "lentic" refers to standing or stagnant water. Lentic water bodies include lakes, ponds, and other bodies of water that have little or no current or flow. This is in contrast to lotic water bodies, such as streams and rivers, which have a continuous flow of water.
