The correct answer is "Rantai makanan" because it refers to the event of eating and being eaten among living organisms in a specific order. It is a concept in ecology that describes the transfer of energy and nutrients from one organism to another through a series of feeding relationships. This term is commonly used to understand the flow of energy and the interdependence of organisms in an ecosystem.

This answer suggests that living organisms have a characteristic of needing each other. This implies that they rely on each other for various reasons such as food, shelter, reproduction, and other forms of support. It highlights the interdependence and interconnectedness of different species in an ecosystem.

Living organisms need an environment for various purposes such as habitat, finding food, and reproducing. However, fighting is not a necessary requirement for their survival. While some organisms may engage in fights for territory or resources, it is not a fundamental need for their existence. Therefore, the correct answer is "Tempat bertarung" (Place to fight).

Cacing tanah berguna bagi manusia karena mereka dapat menyuburkan tanaman petani. Cacing tanah menggali dan mencerna materi organik seperti daun yang jatuh ke tanah, menghasilkan kotoran yang kaya akan nutrisi. Kotoran ini kemudian menjadi pupuk alami yang dapat meningkatkan kesuburan tanah. Dengan demikian, cacing tanah membantu meningkatkan hasil panen petani dan menjaga keseimbangan ekosistem pertanian.

Hewan konsumen tingkat 3 adalah pemakan daging, sehingga disebut sebagai hewan karnivora. Hewan karnivora memiliki kebiasaan makan yang didominasi oleh daging, baik dari hewan maupun serangga. Mereka memiliki gigi-gigi yang tajam dan cakar yang kuat untuk menangkap dan memakan mangsa mereka. Hewan karnivora umumnya tergantung pada hewan herbivora atau omnivora untuk memenuhi kebutuhan makanan mereka.

The correct answer is "Kutu di atas kulit kerbau hilang dimakan burung jalak." This is because the question asks for the benefit obtained by the kerbau that is infested by the burung jalak (mynah bird). The presence of the burung jalak helps the kerbau by eating the lice on its skin, thereby removing the parasites and providing relief to the kerbau.

Lebah membantu dalam proses penyerbukan karena saat mereka mengunjungi bunga untuk mencari nektar, serbuk sari menempel pada tubuh mereka. Kemudian, ketika lebah tersebut mengunjungi bunga lain, serbuk sari yang menempel tadi akan jatuh dan menempel pada putik bunga, yang merupakan bagian betina dari bunga. Proses penyerbukan ini penting untuk reproduksi tanaman dan pembentukan biji.

When the farmers exterminate snakes in the rice fields, the number of rats will increase. This is because snakes are natural predators of rats, and by removing them, there will be fewer predators to keep the rat population in check. As a result, the rat population will likely grow in numbers.

Simbiosis mutualisme adalah hubungan antara dua makhluk hidup yang saling menguntungkan satu sama lain. Dalam hubungan ini, kedua makhluk tersebut saling memberikan manfaat tanpa merugikan satu sama lain. Contohnya adalah hubungan antara lebah dan bunga, di mana lebah mendapatkan nektar sebagai makanan dan bunga mendapatkan bantuan dalam penyerbukan.

The correct answer is "Rumput – belalang – katak – ular – elang." This is the correct order of the food chain, starting with plants (rumput) being eaten by grasshoppers (belalang), which are then eaten by frogs (katak). The frogs are then eaten by snakes (ular), and finally, the snakes are preyed upon by eagles (elang).

If the rats in the rice field become extinct, the next animal that will become extinct is the snake. This is because snakes primarily feed on rats, so if the rat population decreases or disappears, the snakes will not have enough food and their population will also decline.

If the deer in the forest are hunted by humans, it will result in a decrease in the population of tigers. Tigers rely on deer as their primary source of food, so if the deer population decreases, the tigers will have less food available to them. This will ultimately lead to a decline in the number of tigers in the forest.

The correct answer is "Lingkungan biotik." Lingkungan biotik refers to the environment that consists of living organisms such as animals and plants. It includes all the interactions between these organisms and their surroundings. This term is used to describe the ecological system that involves the relationships and dependencies between different species within a specific habitat.

Memasang jala ikan di sungai tidak merusak eksosistem sungai, tetapi sebaliknya dapat membantu dalam pengelolaan sumber daya ikan di sungai tersebut.

Jamur dikatakan merugikan manusia karena kebanyakan jamur dapat menyebabkan penyakit kulit, pelapukan pada meja, dan pembusukan makanan. Namun, beberapa jenis jamur dapat diolah menjadi makanan yang lezat dan bergizi, seperti jamur tiram, jamur shitake, dan jamur kancing. Oleh karena itu, jika jamur diolah dengan benar, mereka dapat menjadi sumber olahan makanan yang bermanfaat bagi manusia.

The correct answer is "Pohon mangga lama-lama akan mati karena benalu yang menyerap sari makanannya." This is because parasitic plants like benalu rely on their host plant, in this case, the mango tree, for nutrients and resources. Over time, the benalu will absorb the nutrients from the mango tree, causing it to weaken and eventually die.

Belut tidak termasuk hewan yang dapat memakan padi dalam ekosistem sawah.

The correct answer is "Batu, tanah, dan air" because these are examples of abiotic factors in an ecosystem. Abiotic factors are non-living components of the environment that can affect the organisms living in it. In this case, rocks (batu), soil (tanah), and water (air) are all non-living elements that play a role in shaping the ecosystem and influencing the organisms that live there.

In a food chain, the role of producers is to convert sunlight, water, and carbon dioxide into energy through the process of photosynthesis. They are the primary source of food and energy for all other organisms in the ecosystem. Padi, being a plant, is a producer as it produces its own food through photosynthesis. Therefore, the correct answer is "Produsen."

Bunga anggrek yang tumbuh menempel pada batang pohon tidak memberikan kerugian pada pohon tersebut. Dalam hubungan ini, bunga anggrek mendapatkan tempat untuk tumbuh dan berkembang, sementara pohon tidak terpengaruh secara negatif. Ini adalah contoh dari simbiosis komensalisme, di mana satu spesies mendapatkan manfaat tanpa memberikan manfaat atau merugikan spesies lainnya.

Cacing perut di tubuh manusia adalah contoh simbiosis parasitisme karena cacing perut memanfaatkan tubuh manusia sebagai inang untuk mendapatkan nutrisi dan tempat tinggal, sementara manusia menjadi terpengaruh negatif oleh keberadaan cacing perut di dalam tubuhnya.

Symbiosis refers to the relationship between two different types of organisms where they live together and interact with each other. This relationship can be beneficial, harmful, or neutral for both organisms involved. It is a term used to describe the interdependence and interaction between different species in an ecosystem. Symbiosis plays a crucial role in maintaining the balance and functioning of ecosystems by promoting cooperation and mutualism among organisms.

The correct answer is "Hutan". The given sequence of "Rumput - belalang - tikus - Ular - Macan" suggests a food chain in which each organism is a predator to the previous one. In a forest ecosystem, grass (rumput) serves as a food source for grasshoppers (belalang), which are then preyed upon by mice (tikus). Snakes (ular) feed on mice, and finally, tigers (macan) are at the top of the food chain, preying on snakes. This sequence of organisms and their interactions is commonly found in forest habitats.

The correct answer is "Tumbuhan" because in an ecosystem, the primary consumers are organisms that directly consume plants for their energy and nutrients. In the context of a rice field ecosystem, the primary consumers would be organisms that feed on the plants grown in the field, such as insects or small herbivores. Therefore, "Tumbuhan" (plants) is the correct answer as they are the main source of food for the primary consumers in this ecosystem.

The correct answer is "Ular" because it is a consumer at the second trophic level. The trophic level refers to the position of an organism in a food chain or food web. In this case, the organisms listed are arranged in a hierarchical manner based on their feeding relationships. The first trophic level consists of producers (in this case, "Padi"), which are able to produce their own food through photosynthesis. The second trophic level consists of primary consumers (in this case, "Ular"), which feed directly on the producers. Therefore, "Ular" is the correct answer as it is the only organism listed that occupies the second trophic level.
