| 中文简介: |
生态与环境模块由John Kiogora Mworia撰写。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，您将通过定义其各种分支和术语来介绍生态学。然后，您将了解生物体如何组织成群体和群落以及控制其随时间变化的因素。生物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各种类型的关系及其影响。了解了生物在人口和社区层面的组织方式后，您将通过研究两个关键的生态系统过程即能量流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学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以森林砍伐，荒漠化和生物多样性丧失为特征的栖息地退化的人类活动的生态影响来结束我们的研究。

| 课程简介: |
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.
