Some foraging models predict that the distance bees travel when foraging will decline as floral density increases, but biologists Shalene Jha and Claire Kremen showed that bees' behavior is inconsistent with this prediction if flowers in dense patches are ______: bees will forage beyond patches of low species richness to acquire multiple resource types.Which choice completes the text with the most logical and precise word or phrase?A. depletedB. homogeneousC. immatureD. dispersed

Explaining the coexistence of various plant and butterfly species is __ to truly understand the region's biodiversity and the forces that sustain or reduce it. Such an understanding will help ecologists devise an appropriate planthat maximizes the limited funding available for conservation and that still allows for future development of the area.3Which choice completes the text with the most logical and precise word or phrase?A criticalB perilousC condemningD analytical

Pollinators—animals like bees and butterflies that carry pollen between plants—are vitally important to an ecosystem by helping plants mate and reproduce. ------ the population of bees and other pollinators has been in steady decline due to the use of toxic pesticides and the destruction of natural habitats. A new study suggests that this has caused plants to evolve to fertilize their own seeds more often.Which choice completes the text with the most logical transition?Moreover,eliminateHowever,eliminateSometimes,eliminateHence,

In tropical rainforests, the dense canopy of broad-leaved evergreen trees creates a shaded and humid environment at ground level. In desert ecosystems, ______ the environment is characterized by open, sparse vegetation, which allows more sunlight to reach the ground and results in a much drier climate. These contrasting environments lead to vastly different adaptations in plant and animal life.Which choice completes the text with the most logical transition?Choose Your AnswerPreviousNextA.in comparison,B.for instance,C.by contrast,D.consequently,

Which sentence from the passage best supports the inference that agrobiodiversity will increase to accommodate for changing conditions?Agrobiodiversityadapted from United States Botanic GardenWhat is agrobiodiversity?     Agrobiodiversity refers to agriculture and biodiversity. Agrobiodiversity includes all the different kinds of plants and animals that people raise for food. It also includes living things in the soil that break down and recycle soil nutrients, as well as bees and other insects that pollinate crops.How people create agrobiodiversity    Over the past 10,000 years, people have created countless varieties of crops and livestock breeds. Each growing season, farmers saved seeds or took cuttings from the plants that grew well in local soils and weather conditions, or that were best able to resist diseases and insect pests. Over time, they developed varieties that produced food under varying environmental conditions. Farmers also alter soils and other parts of the landscape, and this in turn affects biodiversity. The knowledge traditional farmers have about crop varieties is astonishing. In India, for example, people grow, harvest, and cook over 100 varieties of rice!The history of agrobiodiversity     When people first moved to different parts of the world, they took their seeds and farm animals with them. Farmers bred new varieties of crops and livestock that suited the new growing conditions. As people selected crop plants and livestock for different traits, they created new varieties. Consider wild cabbage for example, which is the ancestor of many different food plants. People bred wild cabbage for different plant parts, such as brussels sprouts, which come from lateral buds on wild cabbage; or collards, from wild cabbage leaves; cauliflower, which comes from the flowers of wild cabbage; as well as many others, including broccoli and kohlrabi, which come from wild cabbage stems.     Genes, together with the environment, determine the traits of all living things. Add human ingenuity and experimentation, and you get the diversity of vegetables, fruits, grains, and meats we eat today!
