Question

types of ecosystems
question 1.
the photo below shows mangrove trees growing in a body of water.
mangrove trees live in shallow water, like that shown in the picture. unlike most trees, the water that mangroves grow in is salty. because of this, mangroves are often found on the coast in warm areas.
which of the following ecosystems would a mangrove most likely be found in?
a. saltwater marsh
b. lake
c. pond
d. deep ocean
question 2.
the table below lists some of the common characteristics of three different aquatic ecosystems.
aquatic ecosystems
ecosystem x: salinity - freshwater, common animals - amphibians, ducks, turtles, freshwater fish, other characteristics - small to medium body of water surrounded by land
ecosystem y: salinity - saltwater, common animals - jellyfish, whales, sharks, other characteristics - large body of water separated by continents
ecosystem z: salinity - somewhat salty, common animals - sea birds, shellfish, saltwater crocodiles, other characteristics - partially enclosed body of water where salt and fresh water mix
ecosystem x is most likely a(n) ______.
a. estuary
b. lake
c. saltwater marsh
d. ocean

Explanation:

• Question 1: Mangrove trees live in salty water. Saltwater marshes are coastal areas with salty water, which matches the mangrove's habitat. Lakes (B) and ponds (C) are freshwater ecosystems. The deep ocean (D) has different characteristics (e.g., pressure, light availability) compared to the shallow - water, coastal habitat of mangroves.
• Question 2: Ecosystem X has freshwater salinity. Estuaries (A) have mixed salt - and - freshwater. Saltwater marshes (C) have salty water. Oceans (D) are saltwater. Lakes are freshwater, small - to - medium - sized bodies of water surrounded by land, which matches the description of Ecosystem X.

Answer:

• Question 1: A. saltwater marsh
• Question 2: B. lake
