    What does abiotic factors mean?

    • Biography

    • Obesse

    • Physical or nonliving factors that shape ecosystems

    Correct Answer
    A. Physical or nonliving factors that shape ecosystems
    Explanation
    Abiotic factors refer to physical or nonliving components that influence and shape ecosystems. These factors include elements such as temperature, sunlight, water availability, soil composition, and air quality. They play a crucial role in determining the types of organisms that can survive in a particular environment and the overall functioning of the ecosystem. By understanding and studying abiotic factors, scientists can gain insights into the relationships between organisms and their environment and how ecosystems respond to changes in these factors.

    What does biotic factors mean?

    • Biography facts

    • The biological influences on organisms within an ecosystem

    Correct Answer
    A. The biological influences on organisms within an ecosystem
    Explanation
    Biotic factors refer to the living components of an ecosystem that have an impact on organisms. These factors include interactions between organisms such as predation, competition, and symbiosis, as well as the availability of food, shelter, and resources. Biotic factors play a crucial role in shaping the structure and dynamics of ecosystems, as they determine the survival, growth, and reproduction of organisms within a given environment.

    What is an ecosystem?

    • Someone who echoes in an ice cream system

    • To work together to build a community

    • A collection of all organisms that live in a particular place, together with their nonliving, or physical, environment

    Correct Answer
    A. A collection of all organisms that live in a particular place, together with their nonliving, or physical, environment
    Explanation
    An ecosystem refers to a collection of all organisms, including plants, animals, and microorganisms, that exist in a specific location. This also includes their nonliving surroundings, such as the air, water, soil, and physical features of the environment. The organisms within an ecosystem interact with each other and with their environment, forming a complex web of relationships and dependencies. This definition highlights the interconnectedness and interdependence of living organisms and their physical surroundings within a specific area.

    What does population mean?

    • You're popular in school

    • Groups of individuals that belong to the same species and live in the same area

    • A valley

    Correct Answer
    A. Groups of individuals that belong to the same species and live in the same area
    Explanation
    The correct answer is "groups of individuals that belong to the same species and live in the same area". Population refers to a collection of individuals of the same species that inhabit a specific geographic area. This definition emphasizes the idea that populations consist of multiple individuals of the same species who interact and share a common environment.

    What does niche mean?

    • A name

    • A body ache

    • The full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions

    Correct Answer
    A. The full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions
    Explanation
    Niche refers to the complete range of physical and biological conditions in which an organism lives, as well as the specific way in which the organism utilizes those conditions. It encompasses the habitat, resources, and interactions that are essential for the survival and reproduction of a particular species. The concept of niche highlights the unique role or function that an organism plays within its ecosystem, including its interactions with other species and its adaptation to its environment.

    Rate this question:

  • 7. 

    What does biome mean?

    • The study of earth

    • A earth-like dome

    • A group of ecosystems that have the same climate and similar dominant communities

    Correct Answer
    A. A group of ecosystems that have the same climate and similar dominant communities
    Explanation
    Biome refers to a group of ecosystems that share the same climate and have similar dominant communities. It is a term used in ecology to categorize and describe large-scale ecological communities. Biomes are characterized by their distinct climate, vegetation, and animal life, and they can be found across different regions of the world. This definition aligns with the given answer choice, which accurately describes the concept of biome.

    Rate this question:

  • 8. 

    What are species?

    • A group of organisms so similar to one another that they can breed and produce fertile offspring.

    • A group of individuals that belong to the same species and live in the same area

    • A assemblages or different populations that live together in a defined area

    Correct Answer
    A. A group of organisms so similar to one another that they can breed and produce fertile offspring.
    Explanation
    Species are defined as a group of organisms that share similar characteristics and are capable of interbreeding to produce fertile offspring. This definition is based on the concept of reproductive isolation, where individuals within a species can mate and produce viable offspring, while individuals from different species cannot. This reproductive compatibility is a key factor in distinguishing one species from another. The other options provided in the question, such as a group of individuals belonging to the same species or different populations living together, do not fully capture the concept of species and the ability to produce fertile offspring.

    What is homeostasis?

    • When an organism reacts to its environment

    • When an organism adapts as it lives on

    • When an organism keeps its internal conditions stable

    • When an organism feeds on another organism

    Correct Answer
    A. When an organism keeps its internal conditions stable
    Explanation
    Homeostasis refers to the process by which an organism maintains a stable internal environment despite changes in the external environment. This includes regulating factors such as body temperature, pH levels, and nutrient levels within certain limits. By keeping its internal conditions stable, an organism can ensure that its cells and systems function properly, allowing it to survive and thrive in its environment. The other options, such as reacting to the environment, adapting, or feeding on another organism, do not accurately describe the concept of homeostasis.

    What is one branch of biology?

    • Trignometry

    • Zoology

    • Algebra

    Correct Answer
    A. Zoology
    Explanation
    Zoology is the correct answer because it is a branch of biology that focuses on the study of animals, including their behavior, physiology, classification, and distribution. It involves researching and understanding various aspects of animal life, from their anatomy and genetics to their habitats and ecological roles. Trignometry and algebra, on the other hand, are branches of mathematics and not biology.

    The combination of chemical reactions through which an organism breaks down or builds up materials as it lives is____________.

    Correct Answer
    metabolism
    Metabolism
    Explanation
    Metabolism refers to the combination of chemical reactions in an organism that involve the breakdown or buildup of materials as it carries out its life functions. It is the process by which the body converts food and drinks into energy that is used to perform various activities. Metabolism is essential for maintaining life and regulating bodily functions such as digestion, respiration, and circulation.

    • Sri Lanka

    • Paris

    • Italy

    • Amazon Rain forest

    Correct Answer
    A. Sri Lanka
    Explanation
    The correct answer is Sri Lanka because the question states that the ecologists are studying a rainforest ecosystem, and Sri Lanka is mentioned as one of the options. Therefore, it can be inferred that the ecologists are studying the rainforest ecosystem in Sri Lanka.

    How much does the biosphere extend above earths surface?

    • 25 kilometers

    • 6 inches

    • 8 kilometers

    • 6 kilometers

    Correct Answer
    A. 8 kilometers
    Explanation
    The biosphere extends approximately 8 kilometers above the Earth's surface. The biosphere refers to the zone on Earth where life exists, including the land, water, and atmosphere. It encompasses all ecosystems and organisms, from the deepest parts of the ocean to the highest mountains. The 8-kilometer measurement indicates the vertical extent of the biosphere, suggesting that life can be found up to this height above the Earth's surface.
