Comprehension Passage
Population interactions are essential to natural habitats, where no species exists in isolation. All species, including plants, animals, and microbes, rely on each other for survival, creating complex biological communities. These interactions, known as interspecific interactions, vary widely, being beneficial, detrimental, or neutral to the species involved. For example, predation, competition, mutualism, commensalism, and parasitism are common types of these interactions. Plants need microbes for nutrient cycling and animals for pollination, while animals depend on plants and other organisms for food and shelter. This interdependence highlights the intricate web of life that sustains ecosystems.
Why is the term "sexual deceit" used to describe the way some orchids - like Ophrys - are pollinated?
1
Because the orchid directly benefits from sexual reproduction between bees.
2
Because the orchid flowers produce a perfume that mimics the pheromones of female bees, leading to bee reproduction
3
Because one petal of the orchid mimics the appearance of a female bee, deceiving male bees into attempting mating (pseudocopulation), during which pollination occurs.
4
Because the bees are intentionally spreading their pollen to the orchids in exchange for the chance to mate.
