Asked 25 days ago|12/9/2020 4:02:14 PM. Biotic factors include predation, competition, parasitism and disease. Objective: At the end of the lesson, you should be able to describe how an ecosystem’s biotic potential and environmental resistance can affect population growth. The maximum reproduction rate of a population, under ideal conditions, is called biotic potential. Presentation Summary : Populations capacity for growth. /Length 7 0 R Intrinsic Rate of increase (r) rate a population would grow if unlimited resources. >> >> What is Carrying Capacity? Biotic Potential and Environmental Resistance: Every kind of organism produces more offspring than are necessary for that species to survive. Defined as a populations capacity for GROWTH The circumstances of an ecosystem POPULATIONS OF ORGANISMS In a given area Environmental resistance is... Any or all factors that act to limit the growth of a population /Height 155 Biotic potential and environmental resistance The biological productivity of any body of water or any portion of that body of water is the end result of the interaction of organism present with the surrounding environment.

To explain biotic potential Population It is a group of organisms of the same species living in an area at the same time. %PDF-1.4 [/Pattern /DeviceRGB] This answer has been confirmed as correct and helpful. Abiotic factors include climatic conditions, fire and temperature. Population Dynamics AP Environmental Science Chapter 9, 12 & 13 . If biotic potential is higher than environmental resistance, the population will (increase or decrease) increase. Most of the time, an ecosystem is dependent on the proliferation of keystone species — organisms that play a crucial role in an ecosystem. 1.1_____ 1.2_____ 1.3 _____ CG Code: S11-12LT-lVhj-29 II. 3 0 obj Together, biotic potential and environmental resistance determine the carrying capacity (K): the maximum population of a given species that a particular habitat Environmental resistance can restrict the full expression of the biotic potential of a population by preventing the increment of the individuals of the population. © Aquaculture, 22: 229-268.

Full expression of the biotic potential of an organism is restricted by environmental resistance, any condition that inhibits the increase in number of the population. INTRODUCTION The development of a strategy and tactics for increasing the abundance of a living species requires knowledge of its biotic potential (capacity to increase in abundance under optimum environmental conditions) and environmental resistance (sum total of all environmental factors that prevent the biotic potential from being realized) (Odum, 1971).

Biotic potential, the maximum reproductive capacity of an organism under optimum environmental conditions.It is often expressed as a proportional or percentage increase per year, as in the statement “The human population increased by 3 percent last year.” It can also be expressed as the time it takes for a population to double in size (doubling time). Environmental resistance factors are things that limit the growth of a population. ~��-����J�Eu�*=�Q6�(�2�]ҜSz�����K��u7�z�L#f+��y�W$ �F����a���X6�ٸ�7~ˏ 4��F�k�o��M��W���(ů_?�)w�_�>�U�z�j���J�^�6��k2�R[�rX�T �%u�4r�����m��8���6^��1�����*�}���\����ź㏽�x��_E��E�������O�jN�����X�����{KCR �o4g�Z�}���WZ����p@��~��T�T�%}��P6^q��]���g�,��#�Yq|y�"4";4"'4"�g���X������k��h�����l_�l�n�T ��5�����]Qۼ7�9�`o���S_I}9㑈�+"��""cyĩЈ,��e�yl������)�d��Ta���^���{�z�ℤ �=bU��驾Ҹ��vKZߛ�X�=�JR��2Y~|y��#�K���]S�پ���à�f��*m��6�?0:b��LV�T �w�,J�������]'Z�N�v��GR�'u���a��O.�'uIX���W�R��;�?�6��%�v�]�g��������9��� �,(aC�Wn���>:ud*ST�Yj�3��ԟ��� /Creator (�� w k h t m l t o p d f 0 .
