1320364876 | Productivity is concerned with? | Biomass or the total mass (quantity) of living organisms in a given system and the time period varies from system to system. | 50 | |
1320364877 | In an ecosystem, there are two basic kinds of productivity. | 1. Primary Productions and 2. Secondary productions | 51 | |
1320383947 | Primary Productions | The conversion of inorganic material from the environment to the new organic material at the first trophic level, i.e. photosynthesis and chemosynthesis. | 52 | |
1320383948 | Secondary Production | The accrual of 10 consumer biomass, i.e. the accrual of new organic material at the second trophic level. | 53 | |

1320400255 | Gause's Law | if two species are both trying to acquire the same resource from the environment, then they cannot coexist indefinitely and one or both must adapt, migrate or go extinct. | 63 | |
1320425667 | Resource Partitioning | When species compete for resources within the same habitat, over time they evolve specialized traits allowing them to share the available resources. | 64 | |
1320425668 | Temporal Partitioning | Different times of the day | 65 | |
1320425669 | Spatial Partitioning | Different places within the habitat | 66 | |
1320425670 | Morphological Partitioning | Morphological differentiation happens when two competing species evolve differing morphologies to allow them to use a resource in different ways like water birds and how their bills are all different. | 67 | |
1320425671 | Indicator species | organisms sensitive to the environment and changes like the canary in the coal mine. | 68 | |
1320425672 | Umbrella Species | A designation used mainly to environmental managers, protecting an umbrella species protects all species in that community. | 69 | |

1320425674 | Keystone Species | Their presence is of comparatively greater importance than others in the system since their removal can have disastrous ripple effects. | 71 | |
1320433558 | Interspecific Competition | Occurs when two or more species interact to gain access to the same limited resources. | 72 | |
1320433559 | Endemic Species | Unique to a specific geographic location | 73 | |
