ECOLOGICAL NICHE Ecological niche refers to the unique role a species has in its environment – how it meets its needs for food and shelter, how it survives, and how it reproduces. A niche includes the species’ habitat, the environmental factors necessary for the species’ survival and all ...
Levels of organization in an Biosphere: But there’s more… Groups of organisms of the same species that live together: Populations of different species living in the same place: All biotic (living) and abiotic (non-living) factors in particular area: Abiotic ex: weather, rocks, soil, etc....
S.4). We determined decadal variance in drought (hence, V) by calculating the decadal mean of PPT:PET and its squared variance. We then summed the squared variance for the study period and used this to rank each model (Figs. S.5 and S.6). We then selected four representative models ...
The vertebrate brain emerged more than ~500 million years ago in common evolutionary ancestors. To systematically trace its cellular and molecular origins, we established a spatially resolved cell type atlas of the entire brain of the sea lamprey—a jawl
its classification as an insect feeder. As expected, vampire bats showed ‘limited’ sucrose assimilation, maintaining blood glucose levels below 96 mg dl−1throughout the experiment. Among omnivores,Carollialevels peaked at 10 min (200 mg dl−1) and gradually declined, whereasPhyllo...
Draw a neatly labeled diagram of chloroplast found in leaf, and its role in photosynthesis? What is meant by biofortification? What do you mean by permeability of membrane? Explain with suitable example. Name the types of nitrogenous bases present in the RNA. What are Mangroves? Give examples....

The country is known for its diverse landscapes, which include towering mountains in the north and expansive arid regions in the southwest. It has four distinct seasons: a mild and dry winter (December to February), a hot and dry spring (March to May), a rainy season (June to August),...
Parasitism Mistletoe grows on other trees and inserts its roots into the tree. The mistletoe gets nutrients, but the tree hosts have trouble growing and sometimes die. Predation Predation – when one organism feeds on another Predator – organism that preys on and consumes animals. Prey – an ...
