An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

ROCKS
MOUNTAINS

Answer:
Blue Cypress Lake, originally called Lake Wilmington, is a lake in Indian River County of the Treasure Coast in Florida. It is the largest lake in the Treasure Coast and Indian River County. It is the headwaters lake of the St. Johns River. The sources of water are several creeks from the south (Mudfish Slough, Padget Branch, Holman Canal, and Fisher Creek), two from the west (Trim Creek, Blue Cypress Creek), and Moonshine Bay from the North that flow into the lake. All the water flows out of the lake to the northwest into M Canal and Zigzag Canal. The lake is over 6,500 acres (26 km²) in size, 21 mi (34 km) in circumference, and has an average depth of 8 feet (2 m). The lake is 2,100 acres (8.7 km²) larger than Lake Washington, 27 mi (43 km) north of this lake. The lake's name comes from the blue appearance of the cypress trees as the morning sun's rays reflect off the water. A fishing camp called Blue Cypress Lakeside Cabins is 4 mi (6 km) off State Road 60. The Blue Cypress Village (about 70 units) is south of the small boat canal from the fish camp.
Answer:
Eukarya - (D)
Explanation:
Organisms belonging to the plant kingdom are eukaryotic and multicellular organisms. They have a distinct cell wall made of cellulose. Cells are organised into true plant tissues. Plants contain plastids and photosynthetic pigments such as chlorophyll.

Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
