He digestive, circulatory, respiratory, immune, and excretory systems all work together to maintain homeostasis. discuss how a minor malfunction in one of these systems could lead to major malfunctions in others. if methods were developed to improve the efficiency and effectiveness of one system, what effect might that improvement have on the other systems?

The digestive, circulatory, respiratory and excretory systems interact in supplying matter and energy to body cells and in removing waste. A minor malfunction in one of the systems could lead to major malfunctions in others. It may eventually lead to cell damage or death.

All the cells in the body need oxygen( respiratory system) to maintain functioning--getting energy from food (digestive system) ingested and removing the waste (excretory system).  Also, the respiratory system and excretory systems remove waste products such as carbon dioxide and urine and sweat. If it fails, the body will lose homeostasis.

Methods developed to improve efficiency and effectiveness of one system might help other systems preserve  or improve functioning. If one system is compromised it may be assisted with or replaced by developed methods preventing it from accompanying damage to other systems.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

correct answer is a. and d.
