Answer: B. Invasive species
An invasive species is a species of organisms which is introduced to a new ecosystem and increases in number rapidly. An invasive species complete with the native species for resources and the population of native species being weaker decreases in number, migrate to other locations or extinct. Here, foreign plants can be considered as invasive species because it limited the growth of native species and these foreign plants were only plants left after several growing seasons.
Carnivores' biological traits aid in their ability to hunt. Wolves and other carnivorous mammals have powerful jaws and large, sharp teeth that enable them to seize and tear apart their food. On the other hand, plant-eating animals typically have large molars that aid in the grinding of leaves and grasses.
Carnivores are the largest animals in the world. The blue whale can grow to be 30 meters (100 feet) long and up to 180 tonnes in weight (200 tons). It eats by gulping down large amounts of water and filtering out microscopic krill organisms, which resemble shrimp. About 40 million of the tiny animals, or 3.6 metric tonnes (4 tonnes), can be consumed daily by blue whales.
The polar bear, which mostly consumes seals, is the largest terrestrial carnivore. Sharp claws are a hunting tool for cats like lions, cougars, and other species. Birds with talons, often known as claws, use them to hunt, including hawks and owls. The curved beaks of many carnivorous birds, known as raptors, are used to break apart their prey.
