Hints & Solutions
(d) Grassland ecosystem is a terrestrial ecosystem. It includes various trophic levels. First trophic level $(T_1)$ - Grass Second trophic level $(T_2)$ - Rabbit Third trophic level $(T_3)-$ Crow Fourth trophic level $(T_4)-$ Vulture. If there is no producers (such as a plant), you cannot sea any primary consumers there. That is why trophic levels are important. They show availability of food/energy in a defined ecosystem, complexity of “who eats what”, and dependency of any one to others.
