a. Land plants, water plants
b. Frog, small fish
c. Land plants → grasshopper → mouse → hawk
d. Frog, dragonfly
e. Frog, dragonfly
f. If all frogs suddenly died, the population of small fish would increase due to reduced predation, which could lead to overconsumption of water plants and disrupt the balance of the aquatic ecosystem. Additionally, animals that prey on frogs, like hawks, might face food shortages.
g. Food webs are different from food chains because they show multiple interconnected feeding relationships among organisms in an ecosystem, whereas food chains depict a single linear pathway of energy transfer. Food webs are more useful because they provide a more realistic and comprehensive view of how energy flows through an ecosystem, highlighting the complexity and interdependence of species.
Parent Tip: Review the logic above to help your child master the concept of food chains and food web worksheets.
