Biogeography of Antarctica
A starting point for understanding Antarctica's biogeography is to consider the factors that affect plant productivity and how these factors vary across the continent. Of course, plants grow by making their own food through the process of photosynthesis (they are autotrophs ), and therefore the key factors affecting plant productivity are the ...

Food Chains and Webs
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. Primary consumers, mostly …

Antarctic Marine Food Webs | SpringerLink
Antarctic communities typically exhibit K-strategies but paradoxically there is great environmental variability in the pack-ice zone. Any model of food chain dynamics, or any management strategy, must take into account not only the low efficiency of the food chain but also the variability of its key elements.
