(1) A lion eating a deer and a sparrow feeding on grain are ecologically similar in being consumers
(2) Predator star fish Pisaster helps in maintaining species diversity of some invertebrates
(3) Predators ultimately lead to the extinction of prey species
(4) Production of chemicals such as nicotine, strychnine by the plants are metabolic disorders
The two correct statements are
Options
- A(2) and (3)

D. (1) and (2)
Step-by-step solution
Both lion (carnivore) and sparrow (herbivore) are consumers. The Asteroidea occupy several important roles through out ecology and biology. Sea stars, such as Ochre star (Pisaster achraceus) have became widely known as the example of the keystone species concept in ecology. Most species are generalist predators, eating molluscs such as clams, oysters, etc.
