The use of explosives to catch fish can result in damage to the fish's habitat.

Hewan-hewan bisa menjadi langka disebabkan karena perburuan liar. Illegal hunting or poaching of animals for their body parts or for sport can lead to a decrease in their population, eventually causing them to become endangered or even extinct. This is a major threat to various species around the world and can disrupt the balance of ecosystems. Efforts to combat illegal hunting and promote conservation are necessary to protect endangered animals and preserve biodiversity.

A benda yang dapat menghantarkan panas dengan baik disebut konduktor. Konduktor adalah bahan yang memiliki struktur atom yang memungkinkan panas untuk dengan mudah berpindah melalui bahan tersebut. Ini berarti konduktor dapat menghantarkan panas dengan cepat dan efisien. Isolator, generator, dan orator tidak memiliki kemampuan untuk menghantarkan panas dengan baik seperti konduktor.

If the number of snakes in the rice field ecosystem increases, it is likely that the number of rats will decrease. This is because snakes are natural predators of rats, and an increase in the snake population will result in more predation on rats, leading to a decrease in their numbers.

Radiasi adalah perpindahan panas melalui gelombang elektromagnetik yang tidak membutuhkan medium untuk berpindah. Dalam hal ini, sinar matahari sampai ke bumi melalui radiasi karena panas dari matahari dapat menyebar melalui ruang hampa di luar atmosfera dan mencapai permukaan bumi. Konduksi, konveksi, dan evaporasi melibatkan perpindahan panas melalui medium atau pergerakan partikel-partikel yang berbeda dengan radiasi.

Ekolokasi adalah kemampuan kelelawar untuk menggunakan suara untuk mengetahui letak suatu tempat dan makanan serta mencari jalan.

Teratai dapat terapung di atas air karena memiliki batang yang berongga. Batang berongga memberikan ruang kosong di dalamnya yang memungkinkan teratai untuk mengapung di permukaan air. Ruang kosong ini juga memberikan kekuatan dan stabilitas pada teratai saat terapung di atas air.

Cendana is a rare and endangered plant species in Indonesia. This plant is almost extinct due to overharvesting for its highly valuable and fragrant wood. The demand for cendana wood has caused widespread illegal logging, leading to the decline in its population.

Pelestarian in situ adalah pelestarian yang dilakukan di habitat aslinya. Ini berarti bahwa upaya pelestarian dilakukan di tempat asli spesies atau ekosistem yang terancam punah atau terganggu. Dengan melindungi dan memulihkan habitat aslinya, spesies dapat tetap hidup dan berkembang biak dengan cara alami. Habitat asli juga penting untuk menjaga keseimbangan ekosistem dan memastikan kelangsungan hidup berbagai spesies yang bergantung padanya.

Kayu, kertas, dan kain merupakan contoh dari benda-benda isolator panas. Isolator panas adalah bahan atau benda yang tidak baik dalam menghantarkan panas. Kayu, kertas, dan kain memiliki struktur yang longgar dan banyak mengandung udara di dalamnya, sehingga sulit untuk menghantarkan panas dengan baik. Sebaliknya, konduktor panas adalah bahan atau benda yang baik dalam menghantarkan panas, seperti logam. Mudah panas dan mudah memuai bukanlah penjelasan yang tepat untuk benda-benda tersebut.

An ecosystem refers to a unit of life that consists of a community of living organisms and their interactions with the non-living components of their environment. This definition fits the description given in the question, where there is a mutual relationship between living organisms and their surroundings. A habitat, on the other hand, refers to the specific area or environment where a particular organism lives. While a habitat is a part of an ecosystem, it does not encompass the entire concept of interdependent relationships between living organisms and their environment. Therefore, the correct answer is Ekosistem.

Tumbuhan cocor bebek berkembang biak dengan tunas daun. This means that the plant reproduces by using leaf buds. This method of reproduction involves the growth of new shoots or buds from the leaf nodes of the plant. These buds can develop into new plants when they are separated from the parent plant and given the appropriate conditions to grow.

The given options are all examples of heat transfer through radiation, except for "Air panas yang mendidih" (boiling hot air). Boiling is a form of heat transfer through convection, not radiation.

The correct answer is "Suaka Margasatwa" because it refers to a nature reserve that has a characteristic of diversity and uniqueness of animal species, and requires habitat conservation for their survival.

The given statement suggests that the handle of a cup feels hot when filled with hot water. This indicates that heat is transferred through the handle, which is an example of conduction. Conduction is the transfer of heat through direct contact between two objects or substances.

The given options describe physical developments that occur during puberty in boys. The first option states that the skin becomes smoother, which is a common physical change during puberty. The second option mentions the growth of hair in the armpits and pubic area, which is also a typical physical change in boys during puberty. The third option talks about the growth of mustache, beard, and sideburns, which is another physical change that occurs during puberty in boys. However, the fourth option states that the reproductive organs start producing eggs, which is incorrect as eggs are produced by the female reproductive system, not the male reproductive system.

Konveksi adalah perpindahan panas yang terjadi melalui aliran zat. Ketika panas berpindah melalui konveksi, zat yang panas akan naik ke atas karena menjadi kurang padat, sedangkan zat yang dingin akan turun ke bawah karena menjadi lebih padat. Contoh umum dari konveksi adalah perpindahan panas yang terjadi di dalam air ketika air panas naik ke atas dan air dingin turun ke bawah.

The excessive use of pesticides can lead to water pollution, which in turn can contribute to flooding. When pesticides are applied to crops or fields, they can be washed away by rain or irrigation water and end up in rivers, lakes, or other bodies of water. This can disrupt the natural balance of ecosystems and harm aquatic organisms, leading to an increase in water levels and potentially causing floods. Therefore, excessive pesticide use is a human activity that can contribute to flooding.

The correct answer is "Tunas, tunas daun, umbi lapis, umbi batang, umbi akar, akar tinggal dan geragih." This is because it includes all the methods of vegetative propagation mentioned in the options, such as the formation of new shoots and leaves, the development of specialized underground structures like bulbs and tubers, and the production of new roots. Additionally, the inclusion of "akar tinggal" (root remnants) and "geragih" (runners) further supports the idea of natural vegetative propagation.
