Question
1. Get 2 articles (one each on):
1) interspecific competition
2) intraspecific competition
2.Describe whether competition is:
-exploitative
-interference
3. If exploitative - tell if it is consumption, overgrowth, or pre-emption.
If interference, tell if it is overgrowth, allelopathy, territorial, encounter, overgrowth, or undercutting.
4. Describe the methods used to test competition.
5. What were the characteristics that made the competitors either good or poor ones?
6. Describe the outcome - was there a species that won? Did they coexist?
Explanation / Answer
1. The article id is given below.

2. Competition represents the antagonistic interactions in plant ecology. And it is applied uniformly in all the fields and interference was later used as subdivision of completion together with exploitation. Both competition and exploitation we can see as the mechanisms involved in antagonistic behavior. The mechanism of competition can be described in six terms: consumptive, preemptive, overgrowth, chemical, territorial and encounter. In interspecific interaction, the main cause is variation in temporal, spatial and environmental conditions.
3, The competition observed here is exploitative competition where one species either reduces or more efficiently uses a resource and therefore depletes the availability of the resource for the other species. Interference competition can be ruled out and it was not observed.
consumption exploitation-organisms consuming shared resources
preemption exploitation- sessile organisms take up space, preventing others from occupying that space over growth exploitation- plants over shade other plants
4. The competition are tested using mathematical models. In case of intra specific it is tested using r/K selection theory and in case of Inter specific it is tested using Lottka - Voltera model.
