O nosso planeta é extremamente vasto e ainda está longe de ser completamente explorado. Curiosamente, a maior parte da superfíci

e terrestre é coberta de oceanos e eles permanecem um grande mistério para a humanidade. Pouco se conhece sobre as profundezas do oceano, mas durante a Segunda Guerra, devido ao uso de sonares para detectar submarinos, o homem conseguiu uma série de descobertas a respeito desse ambiente. A respeito dos oceanos, podemos dizer que:
a)os oceanos, apesar de serem extremamente vastos e robustos, possuem a maior parte da fauna em sua superfície, tendo as profundezas praticamente vazias de vida.

b)as profundezas do oceano são conhecidas por serem ambientes prósperos para a vida, com abundância de luz, alimento e poucos predadores, por isso muitos peixes e outras formas de vida habitam lá.

c)os oceanos são muito profundos, possuem um solo arenoso similar a de um deserto plano em seu fundo.

d)existem indícios de que áreas que hoje são oceanos antigamente eram superfície terrestre. Essas alterações podem ser atribuídas ao movimento tectônico das placas.

Ecologists survey the tree species in two forest plots. plot 1 has six different species, and 95 percent of all trees belong to
Kitty [74]

In this case, the plot 1 is very rich in the single species; it is dominated by a particular species, which occupy 95% share. While in the plot 2 are rich in the number of species, it has 5 species occupying 20% share.  

In comparative analysis, it is seen the plot 1 is rich in species, but diversity is very less. While, plot 2 is rich in the diversity of species, as 5 different species are present, but it is not rich in a particular species.

Hence, compared with plot 1, plot 2 has greater species diversity and lower species richness.
