Growth of heterotrophe and autotrophe populations in an isolated terrestrial environment

Abstract

We consider the model, proposed by Dawidowicz and Zalasiński, describing the interactions between the heterotrophic and autotrophic organisms coexisting in a terrestrial environment with available oxygen. We modify this model by assuming intraspecific competition between heterotrophic organisms. Moreover, we introduce a diffusion of both types of organisms and oxygen. The basic properties of the extended model are examined and illustrated by numerical simulations.

On photosynthesis process with the interaction between two types of leaves

“…The process of photosynthesis depends on a water balance, 2,13,14 and the accessibility of water and mineral salts dissolved in it 4,6,15 and on bioenergetic processes 1,5,16,17 (with references therein).…”
