生态与环境模块作者：约翰·基奥戈拉·姆沃利亚。该模块由5个单元组成，每个单元至少有4个学习活动。首先，您将通过定义生态学的各种分支和术语来了解生态学。然后你将了解有机体是如何组织成群体和社区的，以及随着时间的推移影响它们变化的因素。有机体以影响其种群的方式相互作用，因此，我们将研究种群之间的各种类型的关系及其影响。了解了生物体在人口和社区层面的组织方式后，你将通过研究两个关键的生态系统过程，即能量流动和营养循环，来研究它们与环境的相互作用。然后，您将应用所学的生态概念来分析非洲主要植被群落的结构和功能。我们将通过评估导致栖息地退化的人类活动的生态效应来结束我们的研究，其特征是森林砍伐、荒漠化和生物多样性丧失。

Ecology and Environment Module authored by John Kiogora Mworia. The module consists of 5 units, each with at least 4 learning activities. First you will be introduced to ecology by defining its various branches and terminology. You will then learn how organisms are organised into populations and communities and factors governing their change over time. Organisms interact with one another in ways that affect their populations we will therefore study the various types of relationships between populations and their implications. Having understood how organisms are organised at population and community levels you will proceed to look at their interaction with the environment by studying two key ecosystem processes namely the flow of energy and the cycling of nutrients. You will then apply the ecological concepts learned to analyse the structure and function of key African vegetation communities. We will conclude our study by assessing ecological effects of human activity that lead to habitat degradation characterised by deforestation, desertification, and loss of biodiversity.
