Tadpoles grown in ponds with high densities of tadpoles have lower survival and growth rates than tadpoles grown in ponds with lower densities of tadpoles. which interaction between tadpoles grown in high-tadpole-density ponds would most likely cause the decreased survival and growth rates. a. competition b. symbiosis c. commensalism d. mutualism

The correct answer is option (A) competition.

Competition refers to the type of interaction between the species or the organims in which both are harmed. In the above example of tadpoles grown in high-tadpole-density ponds showed decreased survival and growth rates of tadpoles than the tadpoles in lower-tadpole-density pond because of the competition existing between the species of the tadpole in the pond. This type of competition among the same species is called the intraspecific competition. When the number of species of tadpoles are more, it limits the availability of resources like the food, light, space, water and mates. This results in intraspecific competition and the number of tadpoles tend to decrease.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
