ISAT Practice

This resource provides insight into ecosystems, food webs, and the interactions between producers, consumers, and decomposers. Explore the roles of different organisms, the impact of species elimination (e.g., fox hunting), and examine the abiotic and biotic characteristics of various biomes, including tropical rainforests, arctic tundras, and grasslands. Engage with questions about ecosystem balance, plant adaptations in desert biomes, and the relationships within food webs to enhance comprehension of ecological dynamics.
