The miconia plant is not a native plant to hawaii. since its introduction into hawaii 40 years ago, it has become a popular decorative plant. however, this shallow-rooted plant has replaced many of the native deep-rooted plant species and increased the likelihood of landslides on the island. which is one of the best methods of dealing with this invasive plant a ; the plant should be cross-bred with deeper-rooted plants. b ; the plant should be shared with the smaller islands. c ; the plant should be fed to the native livestock on the island. d ; the plant should be uprooted from all regions in the island.

A

Explanation:

A is correct because cross-breeding will allow for deeper roots which in turns decreases the amount of landslides. It isn't B because they aren't doing anything about the plant on that island, not helping anything. For C and D, even if the plant was uprooted or taken out of the ground to be fed to live stock, seeds would still be left in the ground allowing more to grow.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
