Which of these illustrates how ocean and land ecosystems are connected? a. marine turtles eat mats of floating algae and are eaten by sharks. b. krill consume phytoplankton that capture energy by photosynthesis. c. decomposers break down the remains of a squirrel and return its nutrients to the soil. d. a pelican feeds on ocean fish, and crows eat the pelican’s eggs.

The correct answer would be D. A pelican feeds on ocean fish, and crows eat the pelican’s eggs.

Pelican is large water birds which inhabit coastal areas. They mainly feed on varieties of fishes but can also feed on turtles, insects, et cetera.

They form their nests on land, that is, on the ground or in trees or bushes.

The eggs of these birds are eaten by crows which belong to the land ecosystem.

Thus, pelican and crows interconnect the land and marine ecosystems.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
