<span>Both the mushroom and the gecko are heterotrophs: they need to acquire their food from other sources. The tree, on the other hand, is an autotroph--it gains most of its nutritional needs through photosynthesis.</span>
Mushroom is a type of fungi usually grows in moist wet soil, trees bark and gecko is a lizard which belongs to reptile group usually found in rain forests, deserts and mountains. The trait which is common in mushroom and gecko is their mode of nutrient intake. Both mushroom and gecko are hetrotrophic organisms that are dependent on other organisms for their fullfill their food requirements. As, mushroom decomposes dead remains of plants and animals to obtain their own food and gecko feeds upon insects. Trees lacks hetrotrophic mode of nutrition because they are autotrophs (prepare their own food through photosynthesis).
