    Dalam suatu ekosistem tumbuhan hiaju berperan sebagai ........................

    • Pengurai

    • Produsen

    • Konsumen tingkat I

    • Konsumen tingkat II

    • Konsumen tingkat III

    Correct Answer
    A. Produsen
    Explanation
    In an ecosystem, plants play the role of producers. They are able to convert sunlight into energy through the process of photosynthesis. This energy is then used to produce food for themselves and other organisms in the ecosystem. As producers, plants are essential in providing the foundation of the food chain, as they are the primary source of energy for all other organisms.

    Hubungan antara mahluk hidup dengan lingkungannya merupakan masalah penting dalam Biologi, Bidang Pengetahuan yang mempelajari masalah ini disebut ......................................

    • Taksonomi

    • Genetika

    • Ekologi

    • Fisiologi

    • Botani

    Correct Answer
    A. Ekologi
    Explanation
    The correct answer is "ekologi". Ecology is the branch of biology that studies the relationship between living organisms and their environment. It focuses on understanding how organisms interact with each other and with their surroundings, including the physical and biological factors that influence these interactions. By studying ecology, scientists can gain insights into the balance and dynamics of ecosystems, as well as the impact of human activities on the environment.

    Mahluk hidup dan faktor abiotik pada suatu lingkungan merupakan kesatuan yang disebut ...........................

    • Ekosistem

    • Populasi

    • Komunitas

    • Habitat

    • Biom

    Correct Answer
    A. Ekosistem
    Explanation
    An ecosystem refers to the interaction between living organisms (mahluk hidup) and non-living factors (faktor abiotik) in a particular environment. It encompasses all the biotic (living) and abiotic (non-living) components and their interrelationships within a specific area. This term is used to describe the unity and balance between the different elements in an environment, highlighting the interconnectedness and interdependence of all living organisms and their surroundings.

    Dalam ekologi perairan dipelajari hubungan timbal balik antara faktor biotik dan aibiotik . untuk memahami sifat kimia – fisika air diperlukan dasar pengetahuan ilmu-ilmu lain. Dari pernyatana diatas dapat diambil kesimpulan bahwa ............................................

    • Antara biologi dan fisika tidak ada hubungan sama sekali

    • Antara biologi dan kimia tidak ada hubungan sama sekali

    • Biologi lebih banyak berhubungan dengan fisika daripada dengan kimia

    • Ekologi memerlukan konsep biologi fisik dan kimia

    • Konsep fisika dan kimia kurang membantu konsep biologi

    Correct Answer
    A. Ekologi memerlukan konsep biologi fisik dan kimia
    Explanation
    The given statement suggests that in studying the ecology of water, it is necessary to have a basic understanding of the chemical and physical properties of water, as well as knowledge from other sciences. Therefore, the correct answer is that ecology requires concepts from biology, physics, and chemistry.

    KUmpulan seluruh populasi jenis-jenis mahluk hidup yang bersama-sama disuatu daerah tertentu disebut ...................

    • Populasi

    • Individu

    • Komunitas

    • Ekosistem

    • Nisia

    Correct Answer
    A. Komunitas
    Explanation
    The correct answer is "komunitas". Komunitas refers to the collection of all populations of different species that live together in a specific area. It represents the interactions and relationships between different organisms within a particular ecosystem. This term encompasses the idea of a community of organisms coexisting and interacting with one another in a given habitat.

    Kelompok tumbuhan padi yang hidup disebidang sawah, berdasarkan konsep ekologi merupakan suatu .......................

    • Species

    • Individu

    • Ekosistem

    • Komunitas

    • Populasi

    Correct Answer
    A. Populasi
    Explanation
    The correct answer is "populasi". Based on the given information, the question is asking about a group of rice plants that live in a rice field. In ecology, a population refers to a group of individuals of the same species that live in the same area and interact with each other. Therefore, "populasi" is the most appropriate term to describe the group of rice plants in this context.

    Jamur dalam ekosistem berperan sebagai dekomposer dan bukan sebagai produsen hal ini disebabkan .............

    • Jamur hanya hidup ditempat lembab

    • Jamur tidak memiliki klorofil

    • Jamur merupakan tumbuhan yang belum sempurna

    • Jamur mempunyai sifat seperti bakteri pengurai

    • Jamur menghasilkan racun bagi pemangsanya

    Correct Answer
    A. Jamur mempunyai sifat seperti bakteri pengurai
    Explanation
    Fungi, including mushrooms, play a crucial role as decomposers in ecosystems. Unlike plants, fungi do not have chlorophyll, which is necessary for photosynthesis and therefore cannot produce their own food. Instead, fungi obtain nutrients by breaking down organic matter, similar to how bacteria decompose organic material. This characteristic of fungi as decomposers distinguishes them from producers, which are organisms that can produce their own food through photosynthesis.

    Sebuah akuarium yang berisi ikan dan tumbuhan air merupakan suatu ......

    • Ekosistem

    • Habitat

    • Populasi

    • Substrat

    • Komunitas

    Correct Answer
    A. Habitat
    Explanation
    The correct answer is Habitat. A habitat refers to the specific environment in which a particular organism or group of organisms lives and obtains the resources it needs to survive. In this case, the aquarium serves as the habitat for the fish and aquatic plants, providing them with the necessary conditions and resources such as water, food, and shelter.

    Berikut ini yang merupakan produsen pada ekosistem perairan adalah ......................................

    • Fitoflankton

    • Zooplankton

    • Ikan

    • Jamur

    • Bakteri

    Correct Answer
    A. Zooplankton
    Explanation
    Zooplankton adalah organisme mikroskopis yang hidup di perairan dan berperan sebagai produsen pada ekosistem perairan. Mereka merupakan hewan kecil yang memakan fitoflankton dan bakteri yang ada di perairan. Zooplankton juga menjadi makanan bagi hewan-hewan yang lebih besar seperti ikan. Dengan demikian, zooplankton berperan penting dalam rantai makanan perairan dan merupakan produsen utama dalam ekosistem perairan.
