  • 2. 

    Ekosisteme, s obzirom na životnu sredinu, delimo na ....................... i kopnene ekosisteme. 

    Explanation
    Ekosistemi se mogu podeliti na vodene i kopnene ekosisteme u skladu sa njihovom životnom sredinom. Vodeni ekosistemi obuhvataju sve vodene površine kao što su okeani, mora, reke, jezera i močvare. Ovi ekosistemi su karakterisani prisustvom vode kao glavnog faktora koji utiče na njihovu biološku raznolikost i funkcionisanje. S druge strane, kopneni ekosistemi obuhvataju sve kopnene površine kao što su šume, livade, pustinje i planine. U ovim ekosistemima, zemlja je glavni faktor koji utiče na njihovu biološku raznolikost i funkcionisanje.

    Unošenje novih vrsta organizama ne remeti ravnotežu određenih ekosistema

    • Tačno

    • Netačno

    Correct Answer
    A. Netačno
    Explanation
    This statement is incorrect. The introduction of new species can disrupt the balance of certain ecosystems. When a new species is introduced, it can compete with native species for resources, alter food chains, and disrupt the natural interactions between organisms. This can lead to a decline in native species populations and potentially cause the extinction of certain species. Therefore, the introduction of new species can indeed disturb the equilibrium of ecosystems.

    • Tačno

    • Netačno

    Correct Answer
    A. Tačno
    Explanation
    The statement states that the most diverse and richest marine life community is found at a depth of 50 meters. This means that at this specific depth, there is a higher concentration of different species and a greater abundance of marine life compared to other depths.

    Raznovrsnot živog sveta stajaćih voda zavisi od dubine do koje prodire .......................

    Correct Answer
    svetlost
    Explanation
    The diversity of the aquatic life in stagnant waters depends on the depth to which light penetrates. Light is an essential factor for the growth and survival of many organisms in these environments. It provides energy for photosynthesis, which is the primary source of food for many aquatic organisms. The availability of light at different depths determines the types and abundance of plant and algae species, which in turn influence the entire food chain and the overall biodiversity of the ecosystem.

    • žuti lokvanj

    • Vodeni orašak

    Correct Answer
    A. Trska
    Explanation

    Correct Answer
    A. Morska kornjača
    Explanation
    The term "morska kornjača" (sea turtle) does not belong to the group because all the other terms mentioned (pijavica, barska kornjača, vidra, and žaba) are types of animals that live in water or are associated with water habitats, while sea turtles live in the ocean.

    Correct Answer(s)
    A. Lokvanj
    A. Vodeni orašak
    Explanation
    The correct answer is lokvanj and vodeni orašak. These plants have leaves and flowers on long stems that float on the surface of the water, while their roots are anchored to the bottom. Sočivica, vodena paprat, and mešica do not have this characteristic.

    Biljke koje slobodno plutaju po površini vode bez korena pričvršćenih za dno su (označi sve tačne odgovore)

    • Lokvanj

    • Sočivica

    • Vodena paprat

    • šaš

    • Barska perunika

    Correct Answer(s)
    A. Sočivica
    A. Vodena paprat
    Explanation
    The correct answer is sočivica and vodena paprat. These plants are able to freely float on the surface of the water without being anchored to the bottom because they have adaptations that allow them to do so. Sočivica, also known as duckweed, has small leaves that are buoyant and help it stay afloat. Vodena paprat, also known as water fern, has feathery leaves that provide buoyancy and enable it to float on the water's surface.
