Soal Latihan Pengamatan Gejala Alam Biotik Dan Abiotik

The given answer, "Peka terhadap rangsangan" (Sensitive to stimuli), is the correct answer because it accurately describes the characteristic of the plant "daun putri malu" (Mimosa pudica). When the leaves of this plant are touched or stimulated, they immediately fold up or close, which shows their sensitivity to external stimuli. Therefore, this characteristic of being responsive to stimuli is what distinguishes daun putri malu from the other options given.

The correct answer is "Lup". A lup is a tool used to observe and study biotic or abiotic natural phenomena. It is commonly used by scientists, researchers, and nature enthusiasts to closely examine plants, animals, and other elements of the natural environment. With a lup, one can observe and analyze the intricate details and characteristics of various organisms or components of the natural world.

The given passage describes the growth and development of a corn seed into a plant with leaves, roots, flowers, and fruits. This process is commonly known as "tumbuh dan berkembang" in Indonesian, which translates to "grow and develop" in English.

Rumput adalah komponen biotik karena rumput merupakan salah satu jenis tumbuhan yang hidup dan dapat melakukan proses fotosintesis. Komponen biotik merujuk pada organisme hidup yang ada dalam suatu ekosistem, seperti tumbuhan, hewan, dan mikroorganisme. Pasir, batu, dan tanah, di sisi lain, termasuk dalam komponen abiotik karena mereka tidak hidup dan tidak melakukan proses kehidupan.

Batu termasuk komponen abiotik karena merupakan benda mati yang tidak memiliki kehidupan. Komponen abiotik adalah unsur-unsur non-hidup dalam ekosistem, seperti batu, tanah, air, dan udara. Rumput, ayam, dan bakteri tidak termasuk komponen abiotik karena mereka adalah makhluk hidup.

A barometer is a tool used to measure atmospheric pressure. It is commonly used in weather forecasting and also in various scientific experiments and observations. By measuring the air pressure, a barometer can provide valuable information about changes in weather patterns and atmospheric conditions.

The correct answer is "Bergerak" because movement is a characteristic of living organisms, which are part of the biotic component of the environment. In contrast, color, shape, and size are physical attributes that can be found in both living and non-living things.

A pH meter is used to measure the acidity or alkalinity of a substance or environment. It determines the concentration of hydrogen ions in a solution and provides a numerical value on the pH scale. This is important in determining the acidity or alkalinity of an object or its surrounding environment. The other options, such as a compass, barometer, and altimeter, are not suitable for measuring acidity or alkalinity.

The question asks for a characteristic of abiotic symptoms that cannot be observed. Out of the given options, "Gerak" (movement) is the correct answer because abiotic symptoms, such as nutrient deficiency or water stress, do not involve any physical movement or motion. Other options like "Bentuk" (shape), "Ukuran" (size), and "Tekstur" (texture) can be observed or measured in abiotic symptoms. Therefore, "Gerak" is the only characteristic that cannot be observed.

Kamera adalah peralatan yang digunakan untuk mengambil gambar objek-objek yang tidak memungkinkan dibawa ke laboratorium untuk dikaji lebih mendalam atau untuk mengabadikan kegiatan maupun hasil kegiatan yang dilakukan.
