Difference between grasshopper and spider and kingdom, phylum and mode of nutrition. Also different between yam & cassava and mode of propagation and similarities.
The correct answer and explanation is:
Grasshopper vs Spider
Grasshopper and spider differ in several key characteristics. Grasshoppers are insects, belonging to the class Insecta, while spiders are arachnids, belonging to the class Arachnida. Grasshoppers have three body parts: the head, thorax, and abdomen, and six legs. They also have antennae, compound eyes, and wings. Grasshoppers are herbivorous and have specialized mouthparts for chewing plants. On the other hand, spiders have two body parts: the cephalothorax (combined head and thorax) and abdomen. They possess eight legs, no wings, and no antennae. Spiders are carnivorous and primarily feed on insects, using their fangs to inject venom.
Kingdom, Phylum, and Mode of Nutrition
- Kingdom: This is the highest taxonomic rank and classifies organisms into large groups. The main kingdoms are Animalia, Plantae, Fungi, Protista, Monera, and Archaea.
- Phylum: This is the next level below the kingdom, grouping organisms based on major body plans and structural similarities. For example, Chordata (animals with backbones), Arthropoda (insects and arachnids), and Plantae (plants) are all phyla.
- Mode of Nutrition: Organisms can be categorized based on how they obtain nutrients. Autotrophs (like plants) produce their own food through photosynthesis, while heterotrophs (like animals and fungi) depend on other organisms for food. Some organisms, like fungi, can also be saprophytic, obtaining nutrients by breaking down decaying organic material.
Yam vs Cassava
Yam and cassava are both root crops but have distinct differences. Yams belong to the genus Dioscorea and are typically found in tropical regions. They have a rough, dark brown or purple skin with white or purple flesh. Yams are rich in starch, and are often boiled, roasted, or fried. On the other hand, cassava (or manioc) belongs to the genus Manihot, and has a smooth, brown bark with white flesh. Cassava is primarily used as a starch source, and its roots contain cyanogenic glycosides, which must be properly processed before consumption.
Mode of Propagation: Both crops propagate asexually. Yams are grown from tuber pieces, while cassava is typically propagated by planting stem cuttings.
Similarities: Both yam and cassava are starchy crops, grown mainly in tropical regions. They are important food staples in various parts of the world and require similar environmental conditions, such as warm climates and well-drained soils. Additionally, both crops have high carbohydrate content and are used as staple foods in various traditional dishes.
