What are micro-nutrients according to the document?Carbohydrates and proteinsMinerals and vitaminsFats and sugarsWater and saltsQuestion 3 of 204. What is the primary need for nutrition in living organisms?To change colorTo supply energy for workTo produce sunlightTo grow rootsQuestion 4 of 205. Which process allows plants to produce their own food?DigestionPhotosynthesisRespirationAbsorptionQuestion 5 of 206. What type of nutrition do organisms that produce their own food exhibit?HeterotrophicAutotrophicParasiticSaprophyticQuestion 6 of 207. What do heterotrophic organisms depend on for their food?SunlightOther organisms, plants, or animalsSoil mineralsChlorophyllQuestion 7 of 208. What is the chemical equation for photosynthesis mentioned in the document?6 CO2 + 6H2O → C6H12O6 + 6O2CO2 + H2O → O2 + C6H126O2 + C6H12O6 → 6CO2 + 6H2OH2O + O2 → CO2 + glucoseQuestion 8 of 209.

What structure in leaves absorbs sunlight for photosynthesis?StomataChlorophyllXylemPhloemQuestion 10 of 2011. What transports water and minerals from the roots to the leaves in plants?PhloemXylemStomataChloroplastsQuestion 11 of 2012. What does the phloem transport in plants?WaterOxygenFood (glucose)NitrogenQuestion 12 of 2013. How do plants obtain nitrogen for protein synthesis?From sunlightThrough nitrogen fixationFrom carbon dioxideFrom oxygen in the airQuestion 13 of 2014.

What atmospheric event helps fix nitrogen into the soil?RainfallLightningWindSnowQuestion 15 of 2016. What is symbiotic nutrition?Plants producing their own foodTwo organisms living together for mutual nutritional benefitPlants feeding on insectsAnimals eating dead matterQuestion 16 of 2017. What is an example of a symbiotic relationship between fungi and algae?CuscutaLichenLoranthusDroseraQuestion 17 of 2018. Why are parasitic plants like cuscuta completely dependent on their host?They lack rootsThey lack chlorophyllThey cannot absorb waterThey produce too much foodQuestion 18 of 2019. Why is loranthus considered a partially parasitic plant?It has no rootsIt can photosynthesize but takes water and minerals from the hostIt feeds on insectsIt grows independentlyQuestion 19 of 2020.
