Answer: a.Camouflage
Simulation is a deception in the characteristics of the organism which favors it's survival in the environment. Camouflage is a kind of simulation, in which the organism adapt the color or shape according to the surrounding environment in order to remain undetected by a prey and a predator. For example, chameleon is a reptile, which can change it's color according to the surrounding environment. It changes it's color to green in grass and remains brown in the tree bark in order to eat insects and remain undetected from prey and predator population.
Therefore, According to the simulation, camouflage helps predators to survive by allowing them to sneak up on their prey.
Answer:
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
Explanation:
Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
Biotic factors of an ecosystem are all the living organisms that affect other organisms in an ecosystem and include animals, plants, microorganisms, dead organisms, and even animal waste. Example of biotic factors include: Grass as producers (autotrophs).
