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 answer is D. A pelican feeds on ocean fish, and crows eat the pelican’s eggs.

Explanation:

D is a perfectly balanced example of ocean and and ecosystems connect. In this case, the pelican feeding on ocean fish is an example of a non-aquatic organism interacting with an aquatic factor of an oceanic ecosystem. Still, both of these are in the same ocean-related environment. Crows eating the pelican's eggs, on the other hand, is an exemplar of a non-aquatic organism interacting with another non-aquatic organism. However, this time, one of the organisms is from an environment directly affiliated with/affected by the ocean, and one that has also recently consumed an organism from an oceanic ecosystem. The other organism is not directly related to any aquatic environment, and instead dwells within a land ecosystem.

Essentially, there is an organism from an ocean ecosystem, a carrier/carriers between the two ecosystems, and an organism from a land ecosystem. The ocean fish are from an ocean ecosystem, the pelican and its eggs are the carrier(s) between the two ecosystems, and the crows are from a land ecosystem.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
