Final Answer:
Q1 (Food Web): A food web is a network of interconnected food chains that shows how energy and nutrients flow among different organisms in an ecosystem.
Q2 (Snake decrease): If the snake population decreases, the populations of its prey (like mice, frogs, and birds) may increase, while predators of snakes (like hawks and owls) may have less food and their numbers could drop.
Q3 (Equilibrium): An ecosystem is in equilibrium when populations of organisms stay relatively stable over time—births, deaths, and resource availability are balanced.
Q4 (Energy flow): Energy decreases as we move up each step (trophic level) in a food chain or web—only about 10% of the energy is passed on to the next level; the rest is lost as heat or used for life processes.
Q1 (Food Chain): A food chain is a straight-line sequence showing who eats whom, starting from a producer (like grass) and ending with a top predator (like a hawk).
Q2 (Producer): Grass (or any plant that makes its own food using sunlight).
