Question

QUESTION 56 The ecological impacts of warming are manifold. One response has been to reduce seed production my many plants. An example involving phonology and mutualism for this would be: A Warming accelerates the timing of flowering but not the time for arrival by polinators and thus reduces pollination and subsequent sood production An insect increases its metabolic rate from warming, requiring it to eat more plants, which reduces sood production Warming induces greater water stress in the summer and this reduces productivity and seed production D. All of the above QUESTION 57 Comparing the chaparral biome, where Riverside exists, with the desert biome, as found in Palm Springs, CA, which of the following is untrue A Summers in both are hot and winters cool B. Both ecosystems historically experienced extensive fires C. Primary productivity in both biomes are low and limited by precipitation D. Biodiversity is generally low but variable in both ecosystems QUESTION 58 The common edible frog of Europe is a hybrid between two species, Rane lessonce and Raridw . The hybrids were first described in 1758 and have a wide distribution, from France across central Europe to Russia, Both male and female hybrids exist, but when they mate among themselves, they are rarely successful in producing offspring. What can you infer from this information? • A Postzygotic isolation exists between the two frog species. B. Prezygotic isolation exists between the two frog species. These two species are likely in the process of fusing back into one species. The hybrids form a separate species under the biological species concept

Answer 1

ans 56-answer is d ( all of these)above all option factor affected by warming,basically warming means increment in temperature and this unwanted temperature increment will directly or may indirectly affect the biodiversitty.metabolic rate of insects also affected by warming ,warmer temperature increase metabolic rate of insect and due to this they required a more amount of food so ,it will affect the plant because plant are the main source of food .due to water stress ,plant growth and productivity also affected because water is the first requirement of plant to obtain the energy.also ,warming can alter or change the time of flowering.                           answer57-b(both ecosystem historically experience extensie fire)                   answer 58.a
