Although some studies suggested the presence of water on Mars, the planet represents a hostile environment for human habitation. Scientists are currently researching ways to support potential human colonies on the Red Planet. Scientists have created closed ecosystem models that allow them to control factors such as moisture and temperature. In some of these closed ecosystems, plant growth experiments are being run using simulated Mars soil made of volcanic rocks from Earth. Given this information, in three to five sentences, describe one (nonplant) organism that could contribute to an important ecosystem service for this system and describe one ecosystem service that you benefit from due to your local ecosystem that is probably not available on Mars.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
